This paper proposes methods to pre-process questions in the postings before a QA system can find answers in a discussion group in the Internet. Pre-processing includes garbage text removal and question segmentation. Garbage keywords are collected and different length thresholds are assigned to them for garbage text identification. Interrogative forms and question types are used to segment quest...

Introduction Intensity modulated radiation therapy (IMRT) provides the means for improved treatment for a wide variety of cancers. Piggybacked onto 3DCRT and MLC technologies, IMRT has developed quickly, but will undoubtedly see improvements in core hardware and software as well as in peripheral applications such as record and verify, gating, etc. At the core, individual treatment centers shoul...

Allocation of resources to pre-release Quality Assurance (QA) tasks, such as source code analysis, peer review, and testing, is one of the challenges faced by a software project manager. The goal is to find as many defects as possible with the available QA resources prior to the release. This can be achieved by assigning more resources to the more defect-prone artifacts, e.g., components, class...

objective: button mushrooms (agaricus bisporus) are among the most widely produced and consumed mushrooms in the world. generally speaking, mushrooms are of great nutritional value, which due to their high content of moisture and their corruptibility particular attention is required to be paid to their conservation and health. drying is one of the most important ways to preserve the yields with...

germination is a critical stage in the life cycle of plants and often controls population dynamics, with major practical implications. salsola arbusculiformis is one of the most important plants used to prevent soil erosion and a good fodder resource for sheep and goat in the rangelands of iran. however, the species seems to have low seed germination, so the purpose of this study was to investi...

Abstract Question answering (QA) systems provide a way of querying the information available in various formats including, but not limited to, unstructured and structured data natural languages. It constitutes considerable part conversational artificial intelligence (AI) which has led to introduction special research topic on question (CQA), wherein system is required understand given context t...

Question Answering (QA) task is still an active area of research in information retrieval. A variety of methods which have been proposed in the literature during the last few decades to solve this task have achieved mixed success. However, such methods developed in the Arabic language are scarce and do not have a good performance record. This is due to the challenges of Arabic language. QA base...

The process of radiotherapy (RT) is complex and involves understanding of the principles of medical physics, radiobiology, radiation safety, dosimetry, radiation treatment planning, simulation and interaction of radiation with other treatment modalities. Each step in the integrated process of RT needs quality control and quality assurance (QA) to prevent errors and to give high confidence that ...
