This system aids users in managing digital content by intelligently storing and retrieving files based on user input keywords and file types. The system includes a Graphical User Interface and Agent System with UI, Category, and Manager agents for seamless interaction. This innovative solution simplifies the process of deciding where to store files and finding them later on. Current implementation allows testing of agents.

  1. Digital Content Manager Antti Moilanen, Kinoshita Lab anttimo@ka.riec.tohoku.ac.jp

  2. Outline • Introduction • Example problem case • Proposed solution • Construction • Example walkthrough • Summary and future work

  3. 1 Introduction Research plan: • To implement system that helps user to manage digital content Motivation: • Amount of digital content we have to work with is growing everyday • This also means that problems we are having managing it are coming more meaningful and important

  4. 2 Example problem case Storing the file: • User has article Sendai.doc he wrote while being exchange student in Japan. • He has two possible folders to select from: • Articles • Japan • How to decide where to store the file? Sendai.doc ? Articles ? Japan

  5. 2 Example problem case Searching the file: • User decided to save the file to article folder. • Afterwards he thinks it’s in Japan folder but he finds out it isn’t. • How to avoid this problem?

  6. 2 Example problem case We have two main problems: • Deciding where to store a file • How to find the file we are looking for, especially if we already had problem deciding where to save it

  7. 2 Example problem case Conclusion: • To solve mentioned problems, we need system that’s able to: • Decide or help user to decide where to store files • Make finding files easier

  8. 3 Proposed solution Storing file: • Instead of deciding place where to store a file, user gives system keywords that are related to the file • Beside keywords also file-type affects to the saving location • System saves the file and creates metadata which has keywords and information about location of the file Agent System Checks file-type Keywords: Japan Article Checks keywords Sendai.doc Saves file Informs user

  9. 3 Proposed solution Searching files • User gives keywords related to the file he wants to find • Using keywords system searches and gives user files that matched these keywords Agent System Keywords: Japan Article Takes keywords Searches files Sendai.doc

  10. 4 Construction System has two different main parts • Graphical User Interface • Agent system • Agent System • Functions to communicate with GUI • Functions decide where to store files using user input • Functions to find files using user input GUI • Functions to receive user input (file and keywords) • Functions to show feedback from agent system

  11. Category-agent Category-agent Category-agent Category-agent 4 Construction Agent-system: • Based on needed functions agent system is created using three different kind of agents: • UI-agent • Category-agents • Manager-agent Agent System Manager-agent UI-agent GUI

  12. 4 Construction UI-agent • Operates the User Interface i.e. it has base process which creates the graphical user-interface • Has functions to handle messaging between GUI and agent-system

  13. 4 Construction Category-agent • There is multiple amount of category-agents and each of them has set file-types and keywords • Using these it’s accepting or denying files user wants to store • If the file is suitable it makes file-entry which has name of the file and keywords user gave for that file • When searching it’s comparing given keywords to keywords in the file-entries

  14. 4 Construction Manager-agent • Manager-agent is working between two previously mentioned UI- and Category-agents • Broadcasting requests got from UI-agent to categories • Sums up results got when storing or searching file and sends them to UI-agent

  15. 4 Construction Graphical User Interface • GUI is handling communication between user and system: • Providing user input to system • The file user wants to store • Keywords to be attached to this file • Keywords used when searching for a file • Providing feedback from system to user • Did storing or searching succeed or not? • If it didn’t, what went wrong?

  16. 5 Example walkthrough Information about current implementation • Current implementation isn’t yet really saving real files. It’s saving file-entry with filename and keywords into category agent’s working memory • It still enables way to test agents and see if they are working

  17. photos Keywords: sendai, report File-types: gif, jpg documents Keywords: article, report File-types: doc, txt 5 Example walkthrough • File user wants to store: • Sendai.doc • Keywords user sets for this file: • report • article • Current implementation has two category agents:

  18. Storing the file GUI UI Manager _broadcast Documents Photos User- input file :name Sendai :type doc :keywordList (report article) Request-information file :name Sendai :type doc :keywordList (report article) Request-information file :type doc :keywordList (report article) Deny Deny saveStatus :category photos :status "filetype not suitable" saveStatus :category photos :status "filetype not suitable" Inform Inform Category photos: filetype not suitable fileType :suitability OK Store-file file :name Sendai :type doc :keywordList (report article) Inform Inform File :status saved :category documents File :status saved :category documents Inform File sendai.doc was saved successfully into documents category!

  19. Searching the file GUI UI Manager _broadcast Documents Photos User- input keywordList :list (report article) Request-information keywordList :list (report article) Request-file keywordList (report article) Inform Search :status found :category documents :list ((searchResult :list Sendai :type doc)) Inform Search :status found :category documents :list ((searchResult :list Sendai :type doc)) Inform File found from documents category

  20. 6 Summary and future work • Summary: • Current simple implementation works, but should be tested with more categories and file-entries • Future work: • More categories • File browser to GUI so user can actually select a real file he wants to save • Database where files are stored • More options to searching files • File-types • Operators like AND, OR etc. • GUI with better looks and usability • Evaluation of the system by comparing it to same kind of already existing systems
