Bogen, Paul Logasa, Johnston, Joshua, Karadkar, Unmil P., Furuta, Richard and Shipman, Frank (2008): Application of Kalman filters to identify unexpected change in blogs. In: JCDL08 Proceedings of the 8th ACM/IEEE-CS Joint Conference on Digital Libraries 2008. pp. 305-312. Available online
“Information on the Internet, especially blog content, changes rapidly. Users of information collections, such as the blogs hosted by technorati.com, have little, if any, control over the content or frequency of these changes. However, it is important for users to be able to monitor content for deviations in the expected pattern of change. If a user is interested in political blogs and a blog switches subjects to a literary review blog, the user would want to know of this change in behavior. Since pages may change too frequently for manual inspection for "unwanted" changes, an automated approach is wanted. In this paper, we explore methods for identifying unexpected change by using Kalman filters to model blog behavior over time. Using this model, we examine the history of several blogs and determine methods for flagging the significance of a blog's change from one time step to the next. We are able to predict large deviations in blog content, and allow user-defined sensitivity parameters to tune a statistical threshold of significance for deviation from expectation.”

“We describe a novel interface by which a user can browse, bookmark and retrieve previously used working environments, i.e., desktop status, enabling the retention of the history of use of various sets of information. Significant tasks often require reuse of (sets of) information that was used earlier. Particularly, if a task involves extended interaction, then the task's environment has been through a lot of changes and can get complex. Under the current prevailing desktop-based computing environment, after an interruption to the task users can gain little assistance to get back to the context that they previously worked on. A user thus encounters increased discontinuity in continuing extended tasks.”

“Web-based distributed collections often include links to documents that are expected to change frequently, such as blogs. The study reported here demonstrates that blog changes follow specific patterns. The results also illustrate the substantial role of standardized templates in blog pages. These results extend our earlier models that assess the significance of Web page change from a human perspective. These improved models will enable software systems to assist human collection managers in identifying unexpected changes and aberrant events.”

“Traditional implementations provide only limited assistance for locating the information in narrative texts relevant to a certain point of interest. We are investigating providing a "reading wheel" for such purposes. The first step of the bigger picture, as inspired by the editorial compilation of a textbook's index, is an attempt to locate thematically coherent sentences to a given short phrase. In this paper, we propose a two-step methodology to increase the search performance and examine its effectiveness in a test study. We describe the experimental setup and report on the quantitative evaluation of the techniques involved.”

“We describe a multidisciplinary effort in the creation of an electronic repository of poems of John Donne -- the renowned 17th-century English poet. We discuss the workflow we have adopted and the Web-based tools we have developed for maintaining a collection of transcriptions and images, a concordance of poems, a list of press variants, and a browsing interface that enables readers to access these materials. A complement to the multi-volume Variorum Edition of the Poetry of John Donne, this endeavor shows how a traditional scholarly edition can be enhanced by resources made available by computers and the Internet.”

“Shipbuilding treatises are technical manuscripts written in a variety of languages and spanning several centuries that describe the construction of ships. Given their technical content, understanding terms, concepts, and construction sequences is a challenging task. In this paper we describe a scalable approach and a multilingual web-based interface for enabling a group of scholars to edit a glossary of nautical terms in multiple languages.”

“We are exploring the use of image interfaces for testing video-acquired research skills. We studied user performance on three testing image layouts that differ in their use of the available display real estate and in the flexibility of managing the time available to them. Our results confirm that image layout affects user performance on particular tasks and that experts use different strategies from novices. These alternative layouts will be useful for viewing and understanding digital image collections.”

“The Walden's Paths project is developing tools for leveraging student learning with the incredible amount of educational material on the Web. Specialized templates based on established educational frameworks, learning theories, or activities aid path authors in creating pedagogically sound paths by guiding them in collecting and structuring the information included in the path. We describe a template based on the Inquiry-Based Learning educational framework and an implementation that provides support in applying the template to the path authoring process.”

Na, Jin-Cheon and Furuta, Richard (2006): caT: Adapting and updating the Trellis hypertext model. In New Review of Hypermedia and Multimedia, 12 (2) pp. 217-246
“The Trellis project has investigated the structure and semantics of human-computer interaction in the context of hypertext systems. The Trellis model is defined formally using coloured timed Petri nets as the structure of a hyperprogram, and this gives the model an elegant structure that can be both programmed and analysed. In this paper, we review and reexamine the Trellis hypertext model and its implementations to identify ways in which the model can be applied in modern computing environments and to determine improvements that will enhance the usability of the implementations. We discuss issues with Trellis concerning the graphical complexity of specifications, the characteristics of mobile and Web-based environments, and the specifics of its prototypes' user interfaces and implementation platforms. Based on our analyses, we have enhanced the model and extended the earlier systems to produce a new prototype called caT (for context-aware Trellis) which provides a framework for authoring, browsing, and analysis of reasonably complex, dynamic hypertexts. We describe how caT addresses the issues identified in Trellis. We also describe the results of our small usability study of the caT system and discuss matters that we continue to investigate.”

“The MIDAS project is developing infrastructure and policies for optimal display of digital information on devices with diverse characteristics. In this paper we present the preliminary results of a study that explored the effects of scaling and color-depth variation in digital photographs on user perceptions of similarity. Our results indicate general trends in user preferences and can serve as guidelines for designing policies and systems that display digital images optimally on various information devices.”

“Unlike many efforts that focus on supporting scholarly research by developing large-scale, general resources for a wide range of audiences, we at the Cervantes Project have chosen to focus more narrowly on developing resources in support of ongoing research about the life and works of a single author, Miguel de Cervantes Saavedra (1547-1616). This has lead to a group of hypertextual archives, tightly integrated around the narrative and thematic structure of Don Quixote. This project is typical of many humanities research efforts and we discuss how our experiences inform the broader challenge of developing resources to support humanities research.”

Stotts, David and Furuta, Richard (2004): Language-theoretic classification of hypermedia paths. In: Proceedings of the Fifteenth ACM Conference on Hypertext 2004. pp. 40-41. Available online
“Paths are, and have been since the beginning, an important mechanism for organizing hypermedia documents. This note shows how a document defined as a (possibly infinite) collection of paths over content nodes can be succinctly expressed as a formal language. We show the relationship to earlier hypermedia models based on automata. The language-theoretic model can be used to implement path engines as parsers or recognizers. Different levels of path power require different classes of recognizing automata.”

“In the diversifying information environment, contemporary hypermedia authoring and filtering mechanisms cater to specific devices. Display-agnostic hypermedia can be flexibly and efficiently presented on a variety of information devices without any modification of their information content. We augment context-aware Trellis (caT) by introducing two mechanisms to support display-agnosticism: development of new browsers and architectural enhancements. We present browsers that reinterpret existing caT hypertext structures for a different presentation. The architectural enhancements, called MIDAS, flexibly deliver rich hypermedia presentations coherently to a set of diverse devices.”

“Many approaches have been pursued over the years to facilitate creating, organizing, and sharing collections of materials extracted from large information spaces. Little attention, in the context of hypertext collections, has been paid to the addition of new materials to these collections over time. Traditionally, human maintainers manually incorporate new materials into existing collections as they appear in the underlying network. In this paper we address the issues involved in supporting the creation and maintenance of dynamically growing hypertextual collections. We describe a prototype implementation for automatically including additional, relevant materials into Web-based collections. Our prototype uses the metaphor of hypertextual paths, a proven technique for layering metastructure atop existing hypertextual materials, which is particularly well suited to accommodating growing collections.”

In: JCDL04: Proceedings of the 4th ACM/IEEE-CS Joint Conference on Digital Libraries 2004. pp. 160-168. Available online
“Distributed collections of Web materials are common. Bookmark lists, paths, and catalogs such as Yahoo! Directories require human maintenance to keep up to date with changes to the underlying documents. The Walden's Paths Path Manager is a tool to support the maintenance of distributed collections. Earlier efforts focused on recognizing the type and degree of change within Web pages and identifying pages no longer accessible. We now extend this work with algorithms for evaluating drastic changes to page content based on context. Additionally, we expand on previous work to locate moved pages and apply the modified approach to suggesting page replacements when the original page cannot be found Based on these results we are redesigning the Path Manager to better support the range of assessments necessary to manage distributed collections.”

“Collection understanding shifts the traditional focus of retrieval in large collections from locating specific artifacts to gaining a comprehensive view of the collection. Visualization tools are critical to the process of efficient collection understanding By presenting simple visual interfaces and intuitive methods of interacting with a collection, users come to understand the essence of the collection by focusing on the artifacts. This paper discusses a practical approach for enhancing collection understanding in image collections.”

“Graph-centric and node-centric browsing are the two commonly identified hypertext-browsing paradigms. We believe that path-centric browsing, the browsing behavior exhibited by path interfaces, is an independent browsing paradigm that combines useful aspects of the two commonly supported cases. Paths have long been recognized as an effective medium for aggregating and communicating information and have been included in various hypermedia systems as alternate metaphors or supporting tools. The Walden's Paths project promotes path-centric traversal as the primary browsing mechanism over Web-based materials. This paper expands the notion of our paths to include more generalized structures and interconnections across paths. We present an architecture for describing complex networks of such paths. Finally, we discuss the design and present a prototype implementation of the Path Engine, a tool that provides a linear interface for browsing intricately interconnected paths.”

“We discuss application of caT (context-aware Trellis), which extends the Trellis Petri-net-based model of hypertext, towards specification of Web-browsable hypertexts that respond to factors that occur during their use. In addition to characteristics such as a reader's role (e.g., student, teacher, administrator, or parent) and the reader's browsing history, we also include factors that may not have been incorporated as directly before, such as measures of the external environment and the attributes/actions of other simultaneous readers. We use the term "responsive" hypertext to reflect the wide range of relevant factors.”

Scholarly annotations reflect uses that predate digital representations and benefit from formalized structure. Scholarly annotations may originate from a broader set of sources than personal annotations, and their association with texts may result from inferences rather than from explicit specifications.”

In: Hypertext'01 - Proceedings of the Twelfth ACM Conference on Hypertext and Hypermedia August 14-18, 2001, Aarhus, Denmark. pp. 205-214. Available online
“The Web provides access to a wide variety of information but much of this information is fluid; it changes, moves, and occasionally disappears. Bookmarks, paths over Web pages, and catalogs like Yahoo! are examples of page collections that can become out-of-date as changes are made to their components. Maintaining these collections requires that they be updated continuously. Tools to help in this maintenance require an understanding of what changes are important, such as when pages no longer exist, and what changes are not, such as when a visit counter changes. We performed a study to look at the effect of the type and quantity of change on people's perception of its importance. Subjects were presented pairs of Web pages with changes to either content (e.g., text), structure (e.g., links), or presentation (e.g., colors, layout). While changes in content were the most closely connected to subjects perceptions of the overall change to a page, subjects indicated a strong desire to be notified of structural changes. Subjects only considered the simultaneous change of many presentation characteristics as important.”

“Increasingly, digital libraries are being defined that collect pointers to World-Wide Web based resources rather than hold the resources themselves. Maintaining these collections is challenging due to distributed document ownership and high fluidity. Typically a collections maintainer has to assess the relevance of changes with little system aid. In this paper, we describe the Waldens Paths Path Manager, which assists a maintainer in discovering when relevant changes occur to linked resources. The approach and system design was informed by a study of how humans perceive changes of Web pages. The study indicated that structural changes are key in determining the overall change and that presentation changes are considered irrelevant.”

“Walden's Paths was designed to enable teachers to collect, organize, and annotate Web-based information for presentation to their students. Experiences with the use of Walden's Paths in high-school classrooms have identified four needs/issues: (1) better support for the gradual authoring of paths by teachers, (2) support for student authoring of paths including the ability for students to collaborate on paths, (3) more obvious distinction between content of the original source materials and that added by the path author, and (4) support for maintaining paths over an evolving set of source documents. These observed needs have driven the development of new versions of Walden's Paths. Additionally, the experiences with path authoring have led to a conceptualization of meta-documents, documents whose components include complete documents, as a general domain where issues of collaboration, intellectual property, and maintenance are decidedly different from traditional document publication.”

“We present a view of hyperdocuments in which each document encodes its own browsing semantics in its links. This requires a mental shift in how a hyperdocument is thought of abstractly. Instead of treating the links of a document as defining a static directed graph, they are thought of as defining an abstract program, termed the links-automaton of the document. A branching temporal logic notation, termed HTL*, is introduced for specifying properties a document should exhibit during browsing. An automated program verification technique called model checking is used to verify that browsing specifications in a subset of HTL* are met by the behavior defined in the links-automation. We illustrate the generality of these techniques by applying them first to several Trellis documents and then to a Hyperties document.”

While some of the Specimen Browser's implementation details (particularly its unconventional use of a full-text retrieval system to store its database, and its specialized mapping software) are of general interest, it also exhibits properties which designers of similar digital library access systems may find worth considering: support for pattern discovery, use of regularity in hypertext link sources and destinations, and employment of Javascript as an interface simplification mechanism.”

“Presentations frequently include material appropriated from external sources; they may incorporate tabular data from published reports, photographs from books, or clip art from purchased collections. With the growing use of the World-Wide Web to disseminate information, there is the emerging potential for a new style of presentation: one that interprets and organizes materials produced by others and published on-line. Authoring such presentations requires the analysis of the source information. However, current presentation authoring software is designed to support traditional presentations, where analysis is assumed a separate task at best supported by separate software. This paper discusses experiences with using VIKI, a system designed to support information analysis, for the authoring of such presentations. VIKI includes a spatial parser to recognize implicit spatial structure generated during analysis. This paper describes how initial experiences with use for path authoring led to VIKI enhancements, including the adaptation of implicit spatial structure recognition for the creation of presentations.”

“Physical objects are the foundation for many of today's areas of scholarship, research, and education. Because physical objects are tangible, any digital representation of one is an approximation of the object. Knowing how to approximate requires an understanding of the work practices and needs of the library's constituencies. We consider issues arising from the creation of digital libraries based on physical objects, focusing particularly on the characteristics of botanical herbaria and their users.”

“The correct and timely creation of systems for coordination of group work depends on the ability to express, analyze, and experiment with protocols for managing multiple work threads. We present an evolution of the Trellis model that provides a formal basis for prototyping the coordination structure of a collaboration system. In Trellis, group interaction protocols are represented separately from the interface processes that use them for coordination. Protocols are interpreted (rather than compiled into applications) so group interactions can be changed as a collaborative task progresses. Changes can be made either by a person editing the protocol specification "on the fly" or by a silent "observation" process that participates in an application solely to perform behavioral adaptations. Trellis uniquely mixes hypermedia browsing with collaboration support. We term this combination a hyperprogram, and we say that a hyperprogram integrates the description of a collaborative task with the information required for that task. As illustration, we describe a protocol for a moderated meeting and show a Trellis prototype conference tool controlled by this protocol.”

“In many hypertext systems, meaningfully traversing a document depends on capabilities, features, and navigational aids that are part of the browser implementation. For example, if a reader browses to a node that has no out links, then backing up, or "warping" to the table of contents can allow the browsing session to continue. If hyperdocuments are to become interchangeable among hypertext systems, rather than being readable only on the systems from which they are authored, one obvious but complex approach is to try and standardize on (most likely, very many) browsing features and behaviors, forming some standard union of the capabilities of current major implementations. This approach molds (or perhaps restricts) future systems, since new browsing "features" must then be worked into such a standard. An alternate approach, used in this paper, is to de-emphasized browser features and emphasize inherent document structure with browsing semantics. An author should be able to create document structure so that the desired meaningful access patterns are inherently allowed by links rather than by browser capabilities. We present a method of analyzing the browsing properties of a hypertext document by examining the links alone. This method is not specific to any particular hypertext system or document authoring format. With it, an author can be certain that a document will allow particular access patterns when read on any browser implementation that has a single navigation operation: direct link following. The method requires a mental shift in how a hyperdocument is conceived abstractly. Instead of treating the links of a document as defining a static directed graph, they are thought of as defining an abstract program, termed the links-automaton of the document. A branching temporal logic notation, termed HTL*, is introduced for specifying properties a document should exhibit during browsing. An automated program verification technique called model checking is then used to verify that these specifications are met by the behavior of the links-automaton. We illustrate the generality of our technique by applying it first to a Trellis document, and then to a Hyperties document.”

“Many successful hypermedia systems are hand-crafted; creating and navigating their networks of nodes and links is entirely under user control. In other systems, concern for the economics of manually linking large bodies of existing information, coupled with a desire to promote more responsive and reconfigurable interfaces, has spurred the development of automated tools, intensional or virtual structures, automatic node content generation and automatic link discovery. Some claim that, apart from annotation features such as commenting, the significant hypermedia systems of the future will be entirely automated. In this panel we explore the potential and dangers of automating hypermedia.”

Stotts, P. David and Furuta, Richard (1991): Dynamic Adaptation of Hypertext Structure. In: Walker, Jan (ed.) Proceedings of ACM Hypertext 91 Conference December 15-18, 1991, San Antonio, Texas. pp. 219-231. Available online
“A technique is described for adapting the apparent structure of a hypertext to the behavior and preferences exhibited by its users while browsing. Examples are given an implementation of this technique using the timing mechanism in Trellis. In the technique, event durations in a document are altered without actually changing the links in the underlying Petri net. The two extrema of instantaneous events and infinite delays can be used to create apparent node and link deletions and additions, as well as to insert new tokens (loci of activity) into a document. Adaptation of these times is accomplished using a simple data state in which the event timings (and other document properties) are variables, called attributes. As a reader traverses hypertext links, author-supplied adaptation agents are invoked to collect information and possibly change the values of the attributes. Agents encapsulate and effect the criteria for deciding when, and specifically how, a structure should be adapted. Several practical examples illustrate the conclusion of this report: sophisticated alterations do not require a complicated adaptation mechanism, that changing document constants into document variables provides flexibility to this mechanism, and that using a limited simple mechanism is the only hope for retaining analysis of the static and dynamic net properties.”

“In this paper we describe a hypertext translator-generator system that uses XTed, the visual Petri net editor from the {Chi}Trellis hypertext system, to specify the semantic component of a string-to-graph translation. XTed-specified parsers convert general authoring notations into structured {Chi}Trellis documents for browsing. The operative mechanism is termed a pair grammar, in which a string grammar and a graph grammar are paired in a one-to-one correspondence. When an XTed-specified parser reduces by one of its string grammar productions, the corresponding production in its graph grammar is used to generate a portion of the Petri net that implements that syntax. The use of pair grammars in conjunction with the Trellis model results in a general method of defining hypertext structure that is both hierarchical and compositional.”

“We describe an SQL relational database schema for representing the objects in HyperCard, along with a technique for automatically populating this schema from a HyperCard stack using the facilities in HyperTalk with calls to the database manager. The standard relational database query language SQL can then be used to perform more general hypertext searches than are possible with the string search feature found in most hypertext browsing environments. Semiautomatic updates of the content of a hypertext are also possible using SQL updates on the object representations in the database to trigger corresponding HyperCard updates on the objects themselves. We describe a prototype implementation and present several example queries and updates to motivate this approach. These techniques, although demonstrated here specifically using HyperCard and Oracle for Macintosh, are generally applicable to a wide range of hypertext systems and relational databases.”

“We present a formal definition of the Trellis model of hypertext and describe an authoring and browsing prototype called {alpha}Trellis that is based on the model. The Trellis model not only represents the relationships that tie individual pieces of information together into a document (i.e., the adjacencies), but specifies the browsing semantics to be associated with the hypertext as well (i.e., the manner in which the information is to be visited and presented). The model is based on Petri nets, and is a generalization of existing directed graph-based forms of hypertext. The Petri net basis permits more powerful specification of what is to be displayed when a hypertext is browsed and permits application of previously developed Petri net analysis techniques to verify properties of the hypertext. A number of useful hypertext constructs, easily described in the Trellis model, are presented. These include the synchronization of simultaneous traversals of separate paths through a hypertext, the incorporation of access controls into a hypertext (i.e., specifying nodes that can be proven to be accessible only to certain classes of browsers), and construction of multiple specialized (tailored) versions from a single hypertext.”

“We describe our experiences with four separate conversions from paper documents into hypertext and discuss the lessons we have learned. The paper document's organisation affects the ease with which it can be converted and the appropriateness of the resulting hypertext. The form of the paper document's machine-readable 'markup' description affects the ability to transform the structure automatically. Designing the link structures that tie together the parts of the hypertext takes special care in automating, as badly-designed and incorrectly-formed links destroy the integrity of the hypertext. Overall, each of the conversions followed the same basic methodology, providing the handle for the development of 'power tools' that can be applied to simplify subsequent conversions.”
