Media to externalize some knowledge as knowledge resources for their sharing among people across time and space are generally defined as "knowledge media". Distribution of knowledge resources sooner or later forms a huge accumulation of knowledge shared by our society, which activates the reediting and redistribution of knowledge resources, and accelerates their memetic evolution. Meme media are knowledge media with reeding and redistribution functions. Each knowledge consists of its code and mode. The code defines the knowledge itself, while the mode defines the presentation details. For each externalized knowledge, we call its code its genotype, and its external representation including its mode its phenotype. Electronic information media have enabled us to edit multimedia documents through direct manipulation on a WYSIWYG editor. We may consider a similar editor to edit not only multimedia documents but also compound documents with embedded tools and services. The editing denotes the recombination of contents on some medium through direct manipulation. Each recombination of contents should be represented as a phenotype manipulation that defines the corresponding recombination of the genotype representation. In this paper, we will propose a new interpretation of knowledge media and meme media. This will clarify the essential mechanism from the view point of the "phenotype-genotype mapping". We will use this interpretation to review the meme media architecture, and to reformulate how the meme-media architecture can be applied to the Web to make it work as a meme pool.

The contribution of this paper includes three folders: (1) To introduce a topic-oriented query expansion model based on the Information Bottleneck theory that classify terms into distinct topical clusters in order to find out candidate terms for the query expansion. (2) To define a term-term similarity matrix that is available to improve the term ambiguous problem. (3) To propose two measures, intracluster and intercluster similarities, that are based on proximity between the topics represented by two clusters in order to evaluate the retrieval effectiveness. Results of several evaluation experiments in Web search exhibit the average intracluster similarity was improved for the gain of 79.1% while the average intercluster similarity was decreased for the loss of 36.0%.

Sugibuchi, Tsuyoshi and Tanaka, Yuzuru (2005): Interactive web-wrapper construction for extracting relational information from web documents. In: Proceedings of the 2005 International Conference on the World Wide Web 2005. pp. 968-969.
In this paper, we propose a new user interface to interactively specify Web wrappers to extract relational information from Web documents. In this study, we focused on improving user's trial-and-error repetitions for constructing a wrapper. Our approach is a combination of a light-weight wrapper construction method and the dynamic previewing interface which quickly previews how generated wrapper works. We adopted a simple algorithm which can construct a Web wrapper from given extraction examples in less than 100 milliseconds. By using the algorithm, our system dynamically generates a new wrapper from a stream of user's mouse events for specifying extraction examples, and immediately updates a preview result that shows how the generated wrapper extracts HTML nodes from a source Web document. Through this animated display, a user can make a lot of wrapper construction trials with various different combinations of extraction examples by only moving a mouse on the Web document, and reach a good set of examples to obtain an intended wrapper in a short time.

Itoh, Masahiko and Tanaka, Yuzuru (2005): Multispace information visualization framework for the intercomparison of data sets retrieved from web services. In: Proceedings of the 2005 International Conference on the World Wide Web 2005. pp. 970-971.
We introduce a new visualization framework for the intercomparison of more than one data set retrieved from Web services. In our framework, we use more than one visualization space simultaneously, each of which visualizes a single data set retrieved from the Web service. For this purpose, we provide a new 3D component for accessing Web services, and provide a 3D space component, in which data set retrieved from the Web service is visualized. Moreover, our framework provides users with various operations applicable to these space components, i.e., union, intersection, set-difference, cross-product, selection, projection, and joins.

While current Web technologies have allowed us to publish intellectual
assets in world-wide repositories, and to browse the resulting massive
accumulation, we have no effective tools yet to flexibly re-edit and
redistribute such intellectual assets for their reuse in different contexts.
Open Hypermedia Systems addressed the problem of augmenting third-party
applications in 90 s, and more recently Web augmentation. We need extended OHS
technologies for the advanced reuse of Web-published intellectual assets
through re-editing and redistributing them. Meme media and meme pool
technologies will work as such extended Open Hypermedia Systems technologies to
annotate, re-edit, and redistribute Web-published assets. This paper reviews
the IntelligentPad and IntelligentBox meme media architectures together with
their potential applications, and proposes both the use of XML/XSL or XHTML to
define two-dimensional meme media objects. When applied to Web contents, meme
media technologies make the World Wide Web operate as a meme pool, where people
can publish their intellectual assets as Web pages, access some Web pages to
extract some of their parts as meme media objects through drag-and-drop
operations, visually combine these meme media objects together with other meme
media objects to compose new intellectual assets, and publish these assets
again as Web pages. Our framework creates a new vista in the circulation and
reuse of our knowledge represented as multimedia documents and/or application
programs, especially in the field of science.

Fujima, Jun, Lunzer, Aran, Hornbaek, Kasper and Tanaka, Yuzuru (2004): Clip, connect, clone: combining application elements to build custom interfaces for information access. In: Proceedings of the 2004 ACM Symposium on User Interface Software and Technology 2004. pp. 175-184.
Many applications provide a form-like interface for requesting information: the user fills in some fields, submits the form, and the application presents corresponding results. Such a procedure becomes burdensome if (1) the user must submit many different requests, for example in pursuing a trial-and-error search, (2) results from one application are to be used as inputs for another, requiring the user to transfer them by hand, or (3) the user wants to compare results, but only the results from one request can be seen at a time. We describe how users can reduce this burden by creating custom interfaces using three mechanisms: clipping of input and result elements from existing applications to form cells on a spreadsheet; connecting these cells using formulas, thus enabling result transfer between applications; and cloning cells so that multiple requests can be handled side by side. We demonstrate a prototype of these mechanisms, initially specialised for handling Web applications, and show how it lets users build new interfaces to suit their individual needs.

Many of today's Web applications support just simple trial-and error retrievals: supply one set of parameters, obtain one set of results. For a user who wants to examine a number of alternative retrievals, this form of interaction is inconvenient and frustrating. It can be hard work to keep finding and adjusting the parameter specification widgets buried in a Web page, and to remember or record each result set. Moreover, when using diverse Web applications in combination -- transferring result data from one into the parameters for another -- the lack of an easy way to automate that transfer merely increases the frustration. Our solution is to integrate techniques for each of three key activities: clipping elements from Web pages to wrap an application; connecting wrapped applications using spreadsheet-like formulas; and cloning the interface elements so that several sets of parameters and results may be handled in parallel. We describe a prototype that implements this solution, showing how it enables rapid and flexible exploration of the resources accessible through user-chosen combinations of Web applications. Our aim in this work is to contribute to research on making optimal use of the wealth of information on the Web, by providing interaction techniques that address very practical needs.

Ito, Kimihito and Tanaka, Yuzuru (2003): A visual environment for dynamic web application composition. In: Proceedings of the Fourteenth ACM Conference on Hypertext 2003. pp. 184-193.
HTML-based interface technologies enable end-users to easily use various remote Web applications. However, it is difficult for end-users to compose new integrated tools of both existing Web applications and legacy local applications such as spreadsheets, chart tools and database. In this paper, the authors propose a new framework where end-users can wrap remote Web applications into visual components called pads, and functionally combine them together through drag&drop-paste operations. The authors use, as the basis, a meme media architecture IntelligentPad that was proposed by the second author. In the IntelligentPad architecture, each visual component called a pad has slots as data I/O ports. By pasting a pad onto another pad users can integrate their functionalities. The framework presented in this paper allows users to visually create a wrapper pad for any Web application by defining HTML nodes within the Web application to work as slots. Examples of such a node include input-forms and text strings on Web pages. Users can directly manipulate both wrapped Web applications and wrapped local legacy tools on their desktop screen to define application linkages among them. Since no programming expertise is required to wrap Web applications or to functionally combine them together, end-users can build new integrated tools of both wrapped Web applications and local legacy applications.
