Harnessing previously issued queries to facilitate collaborative querying is an approach that can help users in digital libraries and other information systems better meet their information needs. Here, the kernel step is to identify and cluster similar queries by mining the query logs. However because of the short lengths of queries, it is relatively difficult to cluster queries effectively us...

The study of evaluation, affect, and subjectivity is a multidisciplinary enterprise, including sociology, psychology, economics, linguistics, and computer science. A number of excellent computational linguistics and linguistic surveys of the field exist. Most surveys, however, do not bring the two disciplines together to show how methods from linguistics can benefit computational sentiment anal...

In this paper, based on the needs analysis theory, it studies demand conditions of English for Specific Purposes for non-English majors through questionnaires. The survey finds...

Current IT application domains such as web services and autonomic computing call for highly flexible systems, able to automatically adapt to changing operational environments as well as to user needs. We are conducting research on how to build these complex systems in the context of agent-oriented software. This short paper gives an overview of our approach (described in details in [3]) which r...

One of the most difficult aspects of deriving an information management plan for a large knowledge based enterprise is to determine what information people require to do their various tasks as well as help them expand and update their existing knowledge. Achieving this goal can be time consuming. To speed up and yet effectively define information needs, an electronic survey tool was designed to...

Intelligence professionals work with incomplete and noisy data. Their information needs are often hard to express, and almost impossible to get right the first time. This paper describes the GEM pattern language for encoding analysts’ information needs in graphical patterns, and its use in the Link Analysis Workbench (LAW) system to find inexact matches to those patterns in large relational dat...

Gamification refers to the use and combination of game design elements in a nonentertainment-based context. Despite the preliminary success of gamification, nowadays the concept faces some criticism. Most gamification projects do not consider context characteristics and implement elements without considering user needs. This can be observed in the inconsistent combination of elements and the va...

This study aimed to explore how community aged care case managers allocated their time to case management functions, how frequently they performed specific case management activities, and what factors influenced the frequency of their activities. METHODS The study involved 154 survey participa...

The field of health and social care in the UK has been very receptive to systemic thinking in recent years and has been extensively and successfully modelled. This paper describes two trends in health care thinking in the UK which build upon this receptivity and are creating market pulls for whole systems ideas. These are the related areas of health needs analysis and service-line reporting, tw...

The system of distributing financial aid dollars using needs analysis formulae implicitly imposes a financial aid tax on assets. Existing studies provide mixed evidence of the influence of this implicit tax on assets on wealth accumulation. This paper attempts to contribute to the literature on this topic by examining the sensitivity of results to various assumptions, specifications, and catego...
