In this paper, we propose a single lowdimensional representation of a large collection of table and hyponym data, and show that with a small number of primitive operations, this representation can be used effectively for many purposes. Specifically we consider queries like set expansion, class prediction etc. We evaluate our methods on publicly available semi-structured datasets from the Web.

Semi-structured data are commonly represented by labelled graphs. These graphs can be simple or nested. In this paper we present how to model nested semi-structured data in the presence of Web forms. Our motivation is to bring our data model more realistic to capture the richness of Web data. The main purpose of the paper is to provide a mechanism to query nested semi-structured data and web fo...

Knowledge inference from semi-structured data can utilize frequent sub structures, in addition to frequency of data items. In fact, the working assumption of the present study is that frequent sub-trees of XML data represent sets of tags (objects) that are meaningfully associated. A method for extracting frequent sub-trees from XML data is presented. It uses thresholds on frequencies of paths a...

XML and other semi-structured data can be represented by a graph model. The paths in a data graph are used as a basic constructor of a query. Especially, by using patterns on paths, a user can formulate more expressive queries. Patterns in a path enlarge the search space of a data graph and current research for indexing semi-structured data focuses on reducing the search space. However, the exi...

there are several problems associated with the use of indwelling urethra catheters, including urinary tract infections and mechanical problems. infections have been well researched but mechanical problems associated with blockage, leakage of urine and general discomfort have been less investigated. although education of patients and carers on the use of catheters has been recommended, in practi...

BACKGROUND Although the reliability of admission interviews has been improved through the use of objective and structured approaches, there still remains the issue of identifying and measuring relevant attributes or noncognitive domains of interest. In this present study, we use generalizability theory to determine the estimated variance associated with participants, judges and stations from a ...

OBJECTIVE This study evaluates the validity, inter-rater reliability, and stability over 3 months of a semi-structured telephone interview measuring adherence to stimulant treatment, the Stimulant Adherence Measure, against the Medication Event Monitoring System (MEMS). METHODS Clinic-referred children (N=22, age 11.85 +/- 2.1 yrs) using psychostimulants for DSM-IV attention-deficit/hyperacti...
