In terms of its support for resource discovery, social tagging has both proponents and critics. The goal of this paper investigates if tags are an effective means for helping users locate useful resources. Adopting techniques from text categorization, we downloaded Web pages and their associated tags from del.icio.us, and trained Support Vector Machine classifiers to determine if the documents could be assigned to their associated tags. Results from the classifiers in terms of precision, recall and F1 score were mixed, suggesting that that not all tags could be used by public users for resource discovery. Detailed analyses of our results revealed characteristics of effective and ineffective tags for resource discovery. From these, implications for social tagging systems are discussed.","PeriodicalId":356148,"journal":{"name":"2008 International Workshop on Information-Explosion and Next Generation Search","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125214426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, keyword search interface is very flexible. It is hard for a system to decide which node is likely to be chosen as a return node and how much information should be included in the result. To address this challenge, we propose an extension of LCA based XML keyword search. First, to determine a return node, we provide a query syntax that the users can tell the system which node they are really interested in. In case that the users do not explicitly specify return information, our system will automatically analyze and choose appropriate return nodes by inferring from user keywords. Second, to return a meaningful result, we investigate the problem of the return information in the LCA and the proximity search approaches. To this end, we introduce the Lowest Element Node (LEN) and define our simple rules without any requirement on the schema information such as DTD or XML Schema. Our experiment results indicate that our system not only infers the right return nodes but also generates compact and meaningful results.","PeriodicalId":356148,"journal":{"name":"2008 International Workshop on Information-Explosion and Next Generation Search","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131128873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given a set V of objects and a query object q, a RkNN query returns a subset of V such that each element of the subset has q as its kNN member according to a certain similarity metric. Early methods pre-compute NN of each data objects and find RNN. Recent methods introduce index based on the mutual distance between two objects. Our method can find RkNN for any k straightforwardly with constant running cost. It can be applied to any RkNN searches whenever the mutual distance between objects can be figured out. It does not require the triangle inequality even. It is also based on pre-compute information, under the assumptions that secondary storage (hard disk drive) is cheap and the current computers are powerful enough so their spare power can be used to update data offline. We evaluate the efficiency and effectiveness of the proposed method.","PeriodicalId":356148,"journal":{"name":"2008 International Workshop on Information-Explosion and Next Generation Search","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127379328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we discuss the problem of knowledge extraction and agglomeration from repositories of temporal data.

In recent years various approaches to free-form keyword search over RDBMS have been proposed. They can produce results across multiple tuples in different relations according to a query consisting of a set of keywords. However, they just consider keyword search for values in tuple instances. In fact users have requirements to search keywords which may be part of the metadata of the database such as names of relations or attributes. In this paper, we extend keyword search on relational database. We define a tuple with annotation as an extension concept of a conventional tuple. In addition we add proposed weight to tuples. The weight function also cares about metadata information. We implement the query processing scheme in RDBMS in order to prove the proposed approach.","PeriodicalId":356148,"journal":{"name":"2008 International Workshop on Information-Explosion and Next Generation Search","volume":"5105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123724979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Web navigation is realized as follows: when a user browsing some Web content, if the Web content is included in the list of results of past search by people in the community, query strings used in the search are shown to the user. To realize this navigation, the system collects queries to search engines and their results, and builds the search query-URL index. It shows relevant queries from the URL of Web content which is browsed by users based on this index. By looking up this database reversely, it can show related query strings to Web contents. Since the search queries in the community are keywords related to information and knowledge of interest within the community, this navigation reflects implicit knowledge in the community. It is useful especially for community members who are not proficient in search. Such users can learn search expertise by following search strings provided by the system. We implemented this proposed method in two ways. We could display relevant queries for approximately 20% of the browsed Web content in this experiment.","PeriodicalId":356148,"journal":{"name":"2008 International Workshop on Information-Explosion and Next Generation Search","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128972600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Statistical learning is useful because there are many uncertainties in crawling, indexing, ranking, and serving of Web search and the solutions have to be data-driven. In this talk, I will explain how statistical learning technologies are being used in web search.

Fast and accurate video search emerges to be an important issue. The need and main technical challenges for video retrieval are similar to those for the content-based image retrieval (CBIR) problem. Lack of meaningful and comprehensive text annotation means that an approach based on content similarity can be promising; and the differences between an often high-level search intention and the low-level features used in content-based search techniques suggest that content-based video retrieval (CBVR) may also suffer from \"semantic gap\" issues.
