Some measures such as mean average precision and recall level precision are considered as good system-oriented measures, because they concern both precision and recall that are two important aspects for effectiveness evaluation of information retrieval systems. However, such good system-oriented measures suffer from some shortcomings when partial relevance judgments are used. In this paper, we ...

POSTER PAPER. This paper proposes an approach of indexing and retrieving degraded handwritten documents. We present a modified version of the popular Vector Model in information retrieval (IR). Our model incorporates top n candidates from a HR system into the scheme of calculating the term frequency (tf) and the inverted document frequency (idf). Standardized IR Tests show that the proposed app...

We will in this paper present an evaluation of how much stemming improves precision in information retrieval for Swedish texts. To perform this, we built an information retrieval tool with optional stemming and created a tagged corpus in Swedish. We know that stemming in information retrieval for English, Dutch and Slovenian gives better precision the more inflecting the language is, but precis...

It is well-established in memory research that retrieval fosters learning. When applying this effect in education, it is an important question which type of retrieval task works best. Several studies have shown that learning is enhanced by linking new information with prior knowledge. A potential approach to making retrieval more effective, therefore, is to enrich retrieval instructions with th...

-Recall and Precision have become the principle measures of the effectiveness of information retrieval systems. Inherent in these measures of performance is the idea of a relevant document, Although recall and precision are easily and unambiguously defined, selecting the documents relevant to a query has long been recognized as problematic. To compare performance of different systems, standard ...

CONTEXT Patient recall of treatment information is a key variable towards chronic disease (CD) management. It is unclear what communication and patient participation characteristics predict recall. OBJECTIVES To assess what aspects of doctor-patient communication predict patient recall of medication information. To describe lifestyle treatment recall, in CD primary care patients. DESIGN Obs...

In many low and middle income countries (LMIC), workers' and consumers' only access to risk and hazard information in relation to the chemicals they use or work with is on the chemical label and safety data sheet. Recall of chemical hazard information is vital in order for label warnings and precautionary information to promote effective safety behaviors. A literature review, therefore, was con...

although filling the gap in reading comprehension gained momentum with the rise of the top-down approach, vygotsky’ concept of scaffolding and the dual code  theory provided a strong support for the use of paratext to enhance comprehension. scaffolding is dependent on other-regulation, one type of which is object-regulation. from this vantage-point, various types of paratext can function as sou...
