This ontology is employed along with user profile information, to automatically select and deliver appropriate information units from a database. Specifically, the focus is on multimedia audio databases. We are developing a Personal AudioCast system at the USC Integrated Media Systems Center which creates and delivers to an end-user personalized audio programs constructed from an audio database. Techniques are developed to segment and structure audio information, process user requests to generate custom audio results, create and optimize SQL queries, and present the results to the user.","PeriodicalId":426762,"journal":{"name":"Proceedings IEEE Advances in Digital Libraries 2000","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123232450","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}

WebSSQL has several unique features. First, WebSSQL assumes that each Web page is a multimedia document consisting of structured data, text data and possibly image data. Second, WebSSQL treats each page as a node in a directed graph composed of many Web pages and links among them. Third, WebSSQL is similarity-based meaning that the retrieved Web pages will be ranked based on their closeness to a given query. The traditional SQL does not support similarity-based retrieval and ranking. With WebSSQL, users can specify their search needs more precisely, leading to more accurate retrieval of useful information.","PeriodicalId":426762,"journal":{"name":"Proceedings IEEE Advances in Digital Libraries 2000","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125788396","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}

Knowledge about the structure of documents is an additional resource that should be exploited during retrieval since the semantics of the different textual objects can be used to specify an information need much more precisely. However the traditional probabilistic retrieval model lacks the ability to handle structural information. We define a new retrieval function based on the probabilistic model which overcomes this drawback. The presented query language allows the assignment of structural roles to individual terms. The efficient evaluation of queries in this framework requires appropriate index structures. We design text and structure indexes and show how their information is combined during evaluation. The implementation supports additional functionalities such as a table of contents for browsing. First evaluation results show the feasibility of the approach on collections of unstructured documents.","PeriodicalId":426762,"journal":{"name":"Proceedings IEEE Advances in Digital Libraries 2000","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123945856","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}

It can be used as boundaries of searches in large hypertext systems and helps to improve the results of searches concerning specific topics or subject domains. On the current Web, there exist no hypertext contexts that are explicitly represented and can be recognized automatically. However, a search system may provide facilities to help users to form their mental context views and transfer the views to concrete instantiations of hypertext contexts, and then enables users to search in these contexts. This paper describes such a prototype system, with which users call specific hypertext contexts by selecting seed pages and including their descendants and/or ancestors within a certain distance, adding single pages, and excluding pages flexibly when they search and browse on the Web. This work reveals a significant potential to improve Web searching by making use of high-level hypermedia structures.","PeriodicalId":426762,"journal":{"name":"Proceedings IEEE Advances in Digital Libraries 2000","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127758286","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}

Since collections of a mediator system are geographically distributed, its performance is mainly influenced by data transmission time between the mediator and its collections. Existing mediator systems employ a result cache that is composed of the results of previously issued queries to reduce this transmission time. However, these systems do not support a general Boolean query model but only simple ones such as a conjunctive query or a single keyword query, etc. In this paper, we propose a new method to efficiently process general Boolean queries using a result cache for mediator systems. A way of semantically partitioning the given result cache in order to reduce the complexity of inference is also presented.","PeriodicalId":426762,"journal":{"name":"Proceedings IEEE Advances in Digital Libraries 2000","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122654728","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}

Much less experimental work has been devoted to studying the effects of WRE in spoken query processing in IR. It is easy to hypothesize that given the typical length of the user query, the effects of WRE in spoken queries on the performance of IR systems must be destructive. The experimental work reported tests this. The paper reports on the background of the study, on the construction of a suitable test collection, on the first experimental results obtained and on the limitations of the study. The results show that classical IR techniques are quite robust to considerably high levels of WRE rates in spoken queries (roughly below 40%), in particular for long queries.","PeriodicalId":426762,"journal":{"name":"Proceedings IEEE Advances in Digital Libraries 2000","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133898555","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}

The geo-spatial community is diverse and its members are spread around the world. The user's task of searching for and locating datasets of interest, would be greatly simplified if a single point of entry could search for datasets from multiple, independent catalogue systems-an interoperable catalogue system. Advances in middleware for distributed systems now make it straightforward to invoke remote catalogues. However semantic interoperability is still a challenge due to different catalogue systems employing different metadata standards. A metadata standard is a collection of attributes used to describe datasets. This paper employs ontologies as a framework to classify semantic mismatches between metadata standards before resolving them. Using ontologies provides a deeper understanding of the semantic mismatches. In addition, both an architecture for an interoperable catalogue system and the implementation of mediators, the component which resolves semantic mismatches, are described. The implementation uses emerging Web technologies such as XML and XSLT. To demonstrate the appropriateness of the approach, this paper shows how semantic mismatches are resolved between two well-established and widely used metadata standards; the ANZLIC (Australia and New Zealand Land information Council) metadata standard and the DIF (Directory Interchange Format) metadata standard.","PeriodicalId":426762,"journal":{"name":"Proceedings IEEE Advances in Digital Libraries 2000","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133875254","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}
