WSS’06 IntroductionIntroduction

„ Design and Implementation of a Web-based Collaboration Support System (RCSS) „ Using Tools for Scientific Research Communities „ A Key Feature of the Developed System ReMarkables is to provides Topic Bookmarks Function to build Research Communities „ The System provides Topic Recommender Function to promote the Research Collaboration

Nippon Institute of Technology 1 AimsAims ofof thethe ResearchResearch

„ To develop an effective Collaboration Support System for Scientific Research Communities „ by improving existing Social Bookmarking Tools as its basis „ since inefficient Information Retrieval from the Web and less Support for Matchmaking in Research Collaboration „ to redesign Social Bookmarking Tools for Scientific Researchers, we apply Agent-based Methodology TROPOS

Nippon Institute of Technology 2 SocialSocial BookmarkingBookmarking ToolsTools (SBT)(SBT)

„ There are two types: „ managing links with social networking flavor „ open and unstructured approach to tagging of resource links „ Links are generally annotated with tags, which are free-form labels assigned by the user „ A number of such tools are used in the Scientific Research Communities, …

„ A free service to help academics to share, store, and organize the academic „ Users can share the personal library with others, and find out who is reading the same papers as them „ This can help users discover literature which is relevant to their field „ CiteULike automatically extracts the details for the links

„ A free online reference management and social bookmarking service for scientists „ A meld of existing reference management conventions and new social bookmarking concepts: „ Online Storage of Bookmarks „ Simple, Non-Hierarchical Organizing using Tags „ Opening the List to Others „ Auto-Discovery of Bibliographic Information

„ An Online Personal Research Collaboration Tool for Academic Researchers „ It aims to build a community where people can collaborate research by: „ retrieve and share bookmarks „ share new events with people „ organize personal search results through bookmarks and tags „ search research work submitted „ collaborate through groups, forums, and private messages

„ To assist Collaborative Activities among members in the communities „ The important characteristic of Community of Practice (CoP) for Research Collaboration in scientific communities is Social/Knowledge Network „ to know “who know what” (i.e., research topic) „ to know “who knows who” (i.e., research group)

„ The important objective of the development is to improve the function of SBT to support research collaboration from its basis „ Based on the functionalities of Connotea and CiteULike, the research also provides the functionalities to support communication among members of a Topic Bookmark List „ The goal is to assist the construction of Community of Practice concerning to a specific topic

Nippon Institute of Technology 11 ArchitecturalArchitectural DesignDesign byby TROPOSTROPOS

„ Global architecture is defined in terms of subsystems (actors), interconnected through data and control flows (data dependencies) „ More system actors are introduced and assigned subtasks and subgoals to the system: „ The overall architectural organization is defined „ The capabilities needed by the actors to fulfill their goals and plans are identified „ A set of agent types is defined and assigned each of them one or more different capabilities

Nippon Institute of Technology 13 TopicTopic RecommenderRecommender

„ When a new topic bookmark list is created from a search result for a specific topic, Topic Bookmarks Manager calls Topic Recommender „ When a member of a topic bookmark list adds a new bookmark attached with some tags representing a topic, Personal Bookmarks Manager calls Topic Recommender „ When a user retrieves online publications specifying a combination of tags, Bookmark Searcher calls Topic Recommender

Nippon Institute of Technology 14 TopicTopic BookmarksBookmarks ManagerManager

„ Another main actor that provides a function to build research community by creating a topic bookmark list „ A Topic Bookmark List is a collection of bookmarks in all personal bookmarks „ the bookmarks have tags defining the topic „ Any user can access to any topic bookmarks „ only the members can read comments on bookmarks of the other members

Nippon Institute of Technology 15 DetailedDetailed DesignDesign

„ Micro level specification of the agents (actors) such as goals, beliefs, and capabilities, as well as communication among agents are specified „ This step strictly related to implementation choice „ We only made detailed design of actors for the new functions, Topic Bookmarks Manager and Topic Recommender „ since we adopted Connotea as a base implementation to develop a prototype system

Nippon Institute of Technology 16 ResultsResults ofof DetailedDetailed DesignDesign

„ Topic Bookmarks Manager has a goal to create a new topic bookmark list from a search result for a specific tags, and to make a mailing list and wiki page associated with the topic „ Topic Recommender has a goal to inform the users who have bookmarks with same tags as the created Topic Bookmarks, that a topic bookmark list is created which may be interesting for the users

Nippon Institute of Technology 17 ImplementationImplementation

„ The Web-based Research Collaboration Support System ReMarkables is implemented as an extension of Connotea „ Connotea is written in and uses MySQL as database „ The main extensions are „ Share Topic Bookmarks function „ Manage Topic Mailing List function „ An experimental prototype system http://comweb.nit.ac.jp/ReMarkables/

Nippon Institute of Technology 18 DiscussionDiscussion

„ The effectiveness of Mailing List as communication tools in Research Collaboration is exemplified for example in Open Source Software (OSS) development community „ The importance of Computational Environment such as Mailing Lists and Distributed Database in collaboration of participants of OSS projects „ The same effect can be recognized in collaboration of participants of RCSS

„ The concept of Topic Bookmarks has its origin in several previous . „ A topic-focused bookmark service for professional groups which presents the specific topic generation process and the autonomous aggregation of information resources „ Topics are formalized as text vectors and documents are categorized according to the users’ interests „ ReMarkables uses tags to specify a topic

„ A social recommendation tool for the WWW that is based upon shared bookmarks „ Peer recommender group is defined as a set of users who are deemed to be similar because their bookmarks (partially) intersect „ Uses pooled bookmarks to reason about user interests via recommender groups and their associated group profiles specified as preferences „ In ReMarkables, the recommendation is sent to the users who has own bookmarks with tags same as the topic bookmarks automatically

Nippon Institute of Technology 21 RelatedRelated Work:Work: AnnoteaAnnotea

„ A shared bookmarks using RDF annotation to group Web documents into informal categories of topics for the purpose of classifying bookmarks „ In contrast, ReMarkables uses tags of each bookmark specified by the user so that there is no need to add any further information such as annotation besides tags

Nippon Institute of Technology 22 ConclusionConclusion

„ The redesigned RCSS ReMarkables provides communication support for the members of Topic Bookmarks as well as information sharing in the topic bookmark list „ The users of ReMarkables can share bookmarks concerning to specific topics while keeping each personal bookmarks private „ The Mailing List associated with a Topic provides a communication tool to build a CoP to promote Research Collaboration
