Full textFlera studier har visat att ordinbäddningsmodeller är användningsbara för många olika språkteknologiuppgifter. Denna avhandling undersöker hur ordinbäddningsmodeller kan användas i sökmotorer för både enspråkig och tvärspråklig domänspecifik sökning. Experiment gjordes för att optimera hyperparametrarna till ordinbäddningsmodellerna och för att hitta det bästa sättet att vikta ord efter hur viktiga de är i dokumentet eller sökfrågan. Dessutom undersöktes metoder för att skapa domänspecifika tvåspråkiga inbäddningar. Systemet jämfördes med en baslinje utan inbäddningar baserad på cosinuslikhet, och för både enspråkiga och tvärspråkliga sökningar var systemet som använde enspråkiga inbäddningar bättre än baslinjen. Däremot var de tvåspråkiga inbäddningarna, särskilt för domänspecifika ord, av låg kvalitet och gav för dåliga resultat för direkt användning inom sökmotorer.

Full textMängden information i de flesta av världens system ökar snabbt. För att kunna hitta relevant information i denna stora mängd data krävs bra informationssökningsalgoritmer (eng: information retrieval, IR). IR-algoritmer kan konstrueras och justeras så att de fungerar bra inom olika sökområden. Ett sådant område är konsumenthälsa, ett område där vanliga människor (konsumenter) söker efter medicinsk information. Ett sätt att förbättra IR-algoritmer är att använda ordinbäddningar (eng: word embeddings, WE). WE är vektorrepresentationer av ord som konstrueras så att liknande ord har liknande vektorer. Tidigare forskning har visat att användning av WE i IR ger lovande resultat. I den här uppsatsen implementeras en IR-algoritm baserad på WE. Detta utvärderas inom området för svenska konsumenthälsofrågor med hjälp av sökloggar från en svensk digital vårdgivare som utvärderingsdata. Den populära BM25-algoritmen användes som referensalgoritm. En linjärkombination av WE-algoritmen och BM25-algoritmen, mixture model (MM), implementerades också. Experimenten avslöjade att en MM som mest liknar WE är att föredra. Vid utvärderingen av dessa tre algoritmer visade det sig att MM algoritmen totalt sett presterade bäst. Fyra olika utvärderingsmått användes och MM-algoritmen var den näst bästa i tre och den bästa i ett. Eftersom MM algoritmen var mest lik WE-algoritmen, indikerar det att användningen av WEi IR har en positiv effekt. Även om ytterligare forskning inom området rekommenderas för att bekräfta dessa preliminära upptäckter, pekar denna uppsats på att WE potentiellt kan förbättra IR inom området svenska konsumenthälsofrågor.

Full textDins del món del Processament del Llenguatge Natural (NLP) i d’altres camps relacionats amb aquest àmbit, les representaciones latents de paraules (word embeddings) s'han convertit en una tecnologia fonamental per a desenvolupar aplicacions pràctiques. En aquesta tesi es presenta un anàlisi teòric d’aquests word embeddings així com alguns algoritmes per a entrenar-los. A més a més, com a aplicació pràctica d’aquesta recerca també es presenten aplicacions per a cerques a la web i màrqueting. Primer, s’introdueixen alguns aspectes teòrics d’un dels algoritmes més populars per a aprendre word embeddings, el word2vec. També es presenta el word2vec en un context de Reinforcement Learning demostrant que modela les normes no explícites (off-policy) en presència d’un conjunt de normes (policies) de comportament fixes. A continuació, presentem un nou algoritme de d’aprenentatge de normes no explícites (off-policy), $word2vec_{\pi}$, com a modelador de normes de comportament. La validació experimental corrobora la superioritat d’aquest nou algorithme respecte \textit{word2vec}. Segon, es presenta un mètode per a aprendre word embeddings que són resistents a errors d’escriptura. La majoria de word embeddings tenen una aplicació limitada quan s’enfronten a textos amb errors o paraules fora del vocabulari. Nosaltres proposem un mètode combinant FastText amb sub-paraules i una tasca supervisada per a aprendre patrons amb errors. Els resultats proven com les paraules mal escrites estan pròximes a les correctes quan les comparem dins de l’embedding. Finalment, aquesta tesi proposa dues tècniques noves (una a nivell de caràcter i l’altra a nivell de paraula) que empren xarxes neuronals (DNNs) per a la tasca de similaritat semàntica. Es demostra experimentalment que aquests mètodes són eficaços per a la predicció de l’eficàcia (click-through rate) dins del context de cerces patrocinades.

Full textBackground: Although research on lexical access in Hebrew-English bilinguals exists, there is a need to quantify and determine if proficiency correlates with scores on language tasks like naming in structurally different languages, such as Hebrew and English. Objective: The aim of this study is to determine if language, test type, and self-reported proficiency is reflected in Hebrew-English bilinguals' naming ability in the two languages. Methods: Twenty healthy Hebrew-English bilinguals completed the Mini Mental State Examination (MMSE), the Language Use Questionnaire (LUQ), the Boston Naming Test (BNT), a Hebrew naming test (Kave, 2005), a 100-item category picture naming task, and category generation in both languages. Results: There was a significant effect of language and test type on accuracy scores on picture naming tests. While language did not have a significant effect on category generation, category had a significant effect on correct words, means semantic cluster score, and mean semantic switching score. There were several language proficiency variables that were significantly correlated with naming tasks in English (Language Ability Rating (LAR), Confidence, Lifetime Exposure, Education History), yet LUQ proficiency variables were only significantly correlated with Kave's test (LAR, Education History) on the Hebrew naming tasks. Conclusion: It appears that confrontation-naming assessments result in more variable performance in English and Hebrew than fluency tests. Based on correlations between LUQ variables and Hebrew naming performance, Kave's test appears to be the only test that captures the unique aspects that allow individuals to be proficient in Hebrew. The BNT is a useful measure for examining English naming. Therefore, using the BNT and Kave's Hebrew naming test appears to be the most effective in measuring naming performance in Hebrew-English bilinguals. Significant LUQ variables in English and Hebrew indicate that self-reported acquisition patterns and lifetime usage provide valuable information regarding naming performance.

Full textSverige får en allt äldre befolkning. Detta för med sig ökande antal personer med Alzheimers sjukdom (AD). Då sjukdomen innebär stor språklig påverkan kan denna patientgrupp förväntas öka inom den logopediska vården. Även andelen flerspråkiga i samhället växer, vilket gör att logopeder kommer att ta emot allt fler flerspråkiga äldre patienter. Ordmobiliseringssvårigheter har setts vara ett tidigt symtom vid sjukdomen både hos enspråkiga och flerspråkiga personer. Tidigare forskning har visat att ett flertal kompensatoriska strategier (t.ex. utfyllnader, omskrivningar och utbyten) används för att hantera dessa svårigheter men det är inte klarlagt hur väl dessa strategier fungerar. Därför undersöks i denna studie vilka kompensatoriska strategier som förekommer både hos enspråkiga och flerspråkiga personer med AD. En fallstudie genomfördes på fyra deltagare med AD, varav två enspråkiga och två flerspråkiga. Spontantal samlades in genom ett semistrukturerat samtal och en kortare berättelse genomfördes med hjälp av bildstöd. Resultaten visade att effektiviteten i de använda strategierna skiljer sig mellan individer. Hur långt deltagarna kommit i sjukdomsförloppet verkade dock ha betydelse. Ingen större skillnad mellan de flerspråkiga deltagarnas båda språk observerades förutom gällande användning av kodväxling. Deltagarna verkade i viss mån vara hjälpta av bildstöd för att uppnå bättre talflyt eftersom ordmobiliseringsproblematiken tycktes minska. Slutsatser som drogs är att logopeder kan medvetandegöra patienter och närstående om ett flertal olika strategier för att hitta den strategi som fungerar bäst för den individuella patienten samt att bildstöd kan användas för att underlätta berättande.

Full textThe present study deals with word frequencies distributions and their relation to probabilistic Information Retrieval (IR) models. We examine the burstiness phenomenon of word frequencies in textual collections. We propose to model this phenomenon as a property of probability distributions and we study the Beta Negative Binomial and Log-Logistic distributions to model word frequencies. We then focus on probabilistic IR models and their fundamental properties. Our analysis reveals that probability distributions underlying most state-of-the-art models do not take this phenomenon into account , even if fundamental properties of IR models such as concavity enable implicitly to take it into account. We then introduce a novel family of probabilistic IR model, based on Shannon information. These new models bridge the gap between significant properties of IR models and the burstiness phenomenon of word frequencies. Lastly, we study empirically and theoretically pseudo relevance feedback models. We propose a theoretical framework which explain well the empirical behaviour and performance of pseudo relevance feedback models. Overall, this highlights interesting properties for pseudo relevance feedback and shows that some state-of-the-art model are inadequate

Full textGiven the amount of Arabic textual information available on the web, developing effective Information Retrieval Systems (IRS) has become essential to retrieve relevant information. Most of the current Arabic SRIs are based on the bag-of-words representation, where documents are indexed using surface words, roots or stems. Two main drawbacks of the latter representation are the ambiguity of Single Word Terms (SWTs) and term mismatch.The aim of this work is to deal with SWTs ambiguity and term mismatch. Accordingly, we propose four contributions to improve Arabic content representation, indexing, and retrieval. The first contribution consists of representing Arabic documents using Multi-Word Terms (MWTs). The latter is motivated by the fact that MWTs are more precise representational units and less ambiguous than isolated SWTs. Hence, we propose a hybrid method to extract Arabic MWTs, which combines linguistic and statistical filtering of MWT candidates. The linguistic filter uses POS tagging to identify MWTs candidates that fit a set of syntactic patterns and handles the problem of MWTs variation. Then, the statistical filter rank MWT candidate using our proposed association measure that combines contextual information and both termhood and unithood measures. In the second contribution, we explore and evaluate several IR models for ranking documents using both SWTs and MWTs. Additionally, we investigate a wide range of proximity-based IR models for Arabic IR. Then, we introduce a formal condition that IR models should satisfy to deal adequately with term dependencies. The third contribution consists of a method based on Distributed Representation of Word vectors, namely Word Embedding (WE), for Arabic IR. It relies on incorporating WE semantic similarities into existing probabilistic IR models in order to deal with term mismatch. The aim is to allow distinct, but semantically similar terms to contribute to documents scores. The last contribution is a method to incorporate WE similarity into Pseud-Relevance Feedback PRF for Arabic Information Retrieval. The main idea is to select expansion terms using their distribution in the set of top pseudo-relevant documents along with their similarity to the original query terms. The experimental validation of all the proposed contributions is performed using standard Arabic TREC 2002/2001 collection

We develop a method for extracting and internalizing web site form submissions which we refer to as web operations. To begin the process, a user performs a sample submission of the form. From that submission, our system determines all of the necessary information to store the web operation. Through a simple user interface the user can view and modify the web operation to the extent that he wants or needs to. With the operation now stored, the user can invoke the operation without browsing to the web site on which the operation was originally contained. By utilizing the web site information extraction techniques contained in the Haystack information management system, we give the user the option to extract information off of web operation results pages. Thus, when using our system to the fullest extent, a user can invoke web operations and view and make use of the results without viewing any web pages.
