Integrated Retrieval over Structured and Unstructured Data

چکیده
We report our experiment results on the INEX 2012 Linked Data Track. We participated in the ad hoc and jeopardy tasks. As the new data collection on INEX 2012 Linked Data Track features a combination of unstructured and structured data, our first attempt is to investigate different strategies of combining the retrievals over structured and unstructured data, and compare the combined approaches with the traditional unstructured ones. In this paper, we discussed three types of combination strategies and we experimented two of them on the track. The experiment results show that ......

Browsing mixed structured and unstructured data
Both structured and unstructured data, as well as structured data representing several different types of tuples, may be integrated into a single list for browsing or retrieval. Data may be arranged in the Gray code order of the features and metadata, producing optimal ordering for browsing. We provide several metrics for evaluating the performance of systems supporting browsing, given some con...
متن کاملIntegrated Semantic Search on Structured and Unstructured Data in the ADOnIS System
We introduce ADOnIS, an information system which coherently integrates two important, yet mostly disparate data sources, namely structured, tabular data, and unstructured data in terms of publications. The integration is achieved by providing the underlying background knowledge of the domains involved in terms of adequately tailored ontologies. Once the two basic data sources are semantically l...

Traditional relational database systems queries works over structured data, whereas information retrieval systems are designed for additional versatile and flexible ranked keyword queries, works over unstructured data, Semistructured, Streamed data, Social networking data and data without any format, known as heterogeneous data. However, several new and emerging applications need data managemen...
متن کاملInformation Theoretic Retrieval with Structured Queries and Documents
Information retrieval through statistical language modeling has become popular thanks to its firm theoretical background and good retrieval performance. One goal of current research on structured information retrieval is thus to extend such models to take advantage of structure information. As a structure may be present on documents or queries or both, we are interested in supporting not only u...
متن کاملAnswering Structured Queries on Unstructured Data
There is growing number of applications that require access to both structured and unstructured data. Such collections of data have been referred to as dataspaces, and Dataspace Support Platforms (DSSPs) were proposed to offer several services over dataspaces, including search and query, source discovery and categorization, indexing and some forms of recovery. One of the key services of a DSSP ...
