چکیده
This paper describes the participation of MRIM team in Task 3: Patient-Centered Information Retrieval-IRTask 1: Ad-hoc search of CLEF eHealth Evaluation lab 2016. The aim of this task is to evaluate the effectiveness of information retrieval systems when searching for health content on the web. Our submission investigates the effectiveness of word embedding for query expansion in the health domain. We experiment two variants of query expansion method using word embedding. Our first run is a baseline system with default stopping and stemming. The other two runs expand the queries using two different word embedding sources. Our three runs are conducted on Terrier platform using Dirichlet language model.

Steganography Scheme Based on Reed-Muller Code with Improving Payload and Ability to Retrieval of Destroyed Data for Digital Images
In this paper, a new steganography scheme with high embedding payload and good visual quality is presented. Before embedding process, secret information is encoded as block using Reed-Muller error correction code. After data encoding and embedding into the low-order bits of host image, modulus function is used to increase visual quality of stego image. Since the proposed method is able to embed...
متن کاملConnected Component Based Word Spotting on Persian Handwritten image documents
Word spotting is to make searchable unindexed image documents by locating word/words in a doc-ument image, given a query word. This problem is challenging, mainly due to the large numberof word classes with very small inter-class and substantial intra-class distances. In this paper, asegmentation-based word spotting method is presented for multi-writer Persian handwritten doc-...
متن کاملConstraining Word Embeddings by Prior Knowledge - Application to Medical Information Retrieval
Word embedding has been used in many NLP tasks and showed some capability to capture semantic features. It has also been used in several recent studies in IR. However, word embeddings trained in unsupervised manner may fail to capture some of the semantic relations in a specific area (e.g. healthcare). In this paper, we leverage the existing knowledge (word relations) in the medical domain to c...
متن کاملA New Document Embedding Method for News Classification
Abstract- Text classification is one of the main tasks of natural language processing (NLP). In this task, documents are classified into pre-defined categories. There is lots of news spreading on the web. A text classifier can categorize news automatically and this facilitates and accelerates access to the news. The first step in text classification is to represent documents in a suitable way t...
متن کاملبررسی تأثیرات ریشهیابی در بازیابی اطلاعات در زبان فارسی
Using the language-specific behavior in information retrieval systems can improve the quality of the retrieved results significantly. Part of the word that remains after removing its affixes is called stem. Stemming process can be used for improving the relevancy of the results in information retrieval system. Different morphological variants of words (plural, past tense…) will be mapped into t...
