  1. A Study of Web Logs for Personalizing the MultiLingual Information Access to The European Library

  2. Outline • The European Library • Web Logs • MultiLingual Information Access (MLIA) • Web Log Analysis • Geographic provenance • Collections usage • Discussion • Conclusion and Future work

  3. The European Library http://www.theeuropeanlibrary.org/ • Provide access to most of the European National Digital Libraries • Many different languages • Resources can be both digital or bibliographical (books, posters, maps, sound recordings, videos, etc.).

  4. The European Library • The European Library collections are suitable for Learning/E-Learning • Quality / Reliability • How the analysis of WEB Log can help in implementing MLIA • Questions we posed at the beginning of our work: • How can E-learning systems deal with collections in different languages? • Are users interested in multilingual/cross-collections instruments? • What are their preferences? • Are them influenced by language?

  5. The European Library • User interaction mainly on the client side • Web Server logs

  6. HTTP Log: structure of the data • W3C Extended Log File Format 2007-01-01 00:04:05 192.87.31.35 GET /Index.html - 80 - 70. *.*.* Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+1.1.4322) - http://www.google.com/search?sourceid=navclient&gfns=1&ie=UTF-8&rls=PCTA,PCTA:2006-33,PCTA:en&q=read+tokyopop+books+online cTargets=collections:a0000,collections:a0037,collections:a0200,collections:a0141,collections:a0010,collections:a0035,collections:a0086,collections:a0132,collections:a0067,collections:a0001,collections:a0062,collections:a0130,collections:a0163,collections:a0211,collections:a0194,collections:a0075,collections:a0073,collections:a0066;+TELSESSID=d551tvd9legbq3rh4l23rjkgh7;+AreCookiesEnabled=889;+cTargetsThemes=theme0 0 0 381 535 203

  7. Log analysis • October 1st 2006 to April 30th 2007 • 22,458,350 Requests • 209,900 different sessions reconstructed using cookies On demand query Logs Log processing

  8. MLIA • MultiLingual Information Access (MLIA) • “possibility for the users of the system to access and search the federated libraries in a personalized way that can allow them to access the collections of documents in their mother tongue and in other preferred languages” • Issues: • Interaction happens outside the system • Logs contain mainly navigational and browsing activity • No control over query sent • MLIA require modifications both on TEL and Digital Libraries services • Control over the central index

  9. Index Index Index Index Index Index Index MLIA • Isolated Query Translation • Translation and Retrieval are separated Translation Component Retrieval Component Translation • Pseudo-translation • Central index translated translation

  10. MLIA • Language to language context (+400 language resources) • Pivot language • Does the user like the query translation approach? • Poor interaction versus rich interaction • When should we prefer direct translation? • User geographical distribution • Collection usage • Language to language preferences • Promoting usage

  11. Session length

  12. Geographic provenance

  13. Collections usage Collection selection Default list First time user

  14. Collections usage

  15. Collections usage

  16. Conclusions • How can E-learning systems deal with collections in different languages? • Isolated query translation versus pseudo-translation • Are users interested in multilingual/cross-collections instruments? • Data showed that there is a demand for multilingual contents and users are interested in more multilingual functionalities • What are their preferences? • The achieved results allowed The European Library to better know users preference about multilingual resources (user distribution, collection selection, …) • Are them influenced by language? • There is a correlation between language and user behavior

  17. Future work: new questions • Do users navigate the portal displaying data in their mother tongue or do they prefer to use the default language (English)? • 80% use the portal as it is • Do English users search only on English collections? • Query language not present in HTTP logs • Action logs • 53475 sessions, 15674 advanced searches, 783 searches based on language • Most ENG,FRE, GER, ITA
