Keyword Search on Large Graphs: A Survey

With the prevalence of Internet access and online services, various big graphs are generated in many real applications (e.g., online social networks and knowledge graphs). An important task on analyzing and mining these graphs is keyword search. Essentially, given a graph G and query Q associated with a set of keywords, the keyword search aims to find a substructure (e.g., rooted tree or subgraph) S in G such that nodes in S collectively cover part of or all keywords in Q, and in the meanwhile, S is optimal on some user specified semantics. Keyword search on graphs can be applied in many real-life applications, such as point-of-interests recommendation and web search facility. In spite of the great importance of graph keyword search, we, however, notice that the latest survey on this topic is far out of date. Consequently, there is prompt need to conduct a comprehensive survey in this research direction. Motivated by this, in this survey, we systematically review graph keyword search studies by classifying the existing works into different categories according to the specific problem definition. This survey aims to provide the researchers a comprehensive understanding of existing graph keyword search solutions.

What should patients do if they miss a dose? A systematic review of patient information leaflets and summaries of product characteristics

Purpose Medicines regulatory authorities advise that patient information leaflets (PILs) should provide specific advice on what actions to take if one or more doses are missed. We aimed to assess the content in this regard, of PILs and Summaries of Product Characteristics (SmPCs) of prescription only medicines (POMs) marketed in the UK. Methods PILs and SmPCs were accessed via the electronic Medicines Compendium. The following terms were used in the advanced search facility: miss(ed), omit(ted), adhere(d), delay(ed), forgot, forget, lapse. Identified documents were screened for instructions on missed doses which were categorised according to level of specificity, and cross-referenced to the National Patient Safety Agency (NPSA) grading of risk of harm from omitted and delayed medicines. Any supporting clinical or pharmacological evidence was identified from SmPCs. Results Two thousand two hundred eighty-four documents were identified from 7248 PILs and SmPCs relating to 1501 POMs. Seven hundred eighty-three (52%) POMs had SmPCs or PILs with no instructions on missed doses; 487 POMs (32%) included non-specific advice (e.g. “take as soon as possible”); 138 (9%) provided specific instructions; and 93 (6%) referred patients to seek medical advice. SmPCs for only 13/138 (9%) of those which included specific instructions provided any supporting clinical or pharmacological evidence. Instructions were absent for several medicines where the NPSA assessed that dose omissions may result in significant risk of harm. Conclusions Advice on missed doses is generally inadequate. Pharmaceutical companies and regulatory authorities should produce clear and concise instructions on what patients should do if they miss doses, with supporting evidence where necessary.

Geotagging: Systematic Anatomization and Conceptual Model for POI Verification

People have been contributing large amount of data every day in Geographical Information Portal however to harness the real power of this tremendous amount of data, it must be managed efficiently. There are some challenges with this data, such as authentication and skewedness. Maximum public places even in a small village must be geotagged to provide better citizen centric services specifically in developing countries. Hence, it’s a need of hour to enrich the unique Indian GIS portal "Bhuvan" with Point of Interest (POI) data where one can find all necessary information. Although POI on Bhuvan is improving day by day however to overcome the challenges mentioned above is an important task. Therefore, a framework is required to expedite the tagging and authentication process of the tagged data in an efficient manner to exploit the power of POI data. In this paper, we have explored the available techniques to improve and verify the crowd sourced data and propose a conceptual model to accomplish the objective of verifying and managing the geotagged data to enrich the portal. A trust rank parameter is introduced to ensure the quality of the POI data. This will be calculated using multisource verification model using state of the art open source technologies available. This verified POI data can be used further in knowledge Graph creation to get better search facility.

KAMUS DIGITAL TANAMAN OBAT MENGGUNAKAN ALGORITMA ROCCHIO BERBASIS MOBILE

Digital dictionaries have been widely used to facilitate word processing and word search through digital media such as mobile phones. Society generally knows the efficacy and how to mix medicinal plants from the experience of previous parents or through books and writings. Searching through books or writings requires a short time compared to searching through digital media, one of which is a digital dictionary. The research aims to create a digital dictionary of mobile-based medicinal plants which has a search facility based on the words entered, for example, the contents of the medicinal plants. The digital dictionary application of medicinal plants uses a search method with the Rocchio algorithm with relevance feedback techniques to check the proximity of the query to the average document relevant to the level of similarity calculation through the stages of tokenizing, filtering, stemming, and Term Weighting with a total data of 200 medicinal plants.

Digital learning of art theory

The purpose of the paper is to substantiate of the pedagogical design of digital education of future art teachers, in particular, the study of art theory in a virtual art class. The essence of the author’s concept is manifested in the metadialogue (oscillation) of two approaches: cluster (focused on statistical visualization of neural a network of genre-style signs outside the spiritual context, i.e. on the “wealth of art”) and semasiological (focused on the anthropological interpretation of these genre-style signs as icons, indexes and symbols, i.e. “wealth of understanding of art”). The proposed project is based on the concept of research-oriented professional education (Inquiry Based Science Education) and technology of advanced learning (Technology Enhanced Learning), which provide bachelors with many opportunities to conduct art research as a performance. The organisation of the design environment of the virtual art class involves non-linear scaffolding in the process of remote virtual experiments on the portal Go-Lab (“Search Facility”, “Inquiry Spaces”, “Related Labs” or the link “Online Labs”); GRAASP environment for the implementation of author’s developments and pedagogically structured programs in the process of performative interaction between teacher and students. The systematic thinking and methodology of the proposed project — the methodology of performative action — implements the phenomenological-hermeneutic method of coherent modeling and expert evaluation of the theory of conceptual integration, connective theory of metaphorical interpretation,the concept of nonlinear epistemology, synthesis, principles of antinomy. The advantage of digital learning in creatively integrated art theory is that in the computer space the student feels unprecedented freedom of creativity and gets unique opportunities for performative action. Thus, the understanding of the causality of historical changes in the theory of art is the result of a performative act, in particular in the laboratory of errors. This requires the introduction of nonlinear logic of functional and meaningful expansion of artistic didactics, implementation of computational visualization technologies, network analysis, thematic intermedia modeling. The visualised results of the study demonstrated the successful integration of performative methodology of cognition as artistic creativity in the process of professional training of future art teachers.

Location based Web Object Search using Probabilistic Classification Model.

The classical Web search engines focus on satisfying the information need of the users by retrieving relevant Web documents corresponding to the user query. The Web document contains the information on different Web objects such as authors, automobiles, political parties e.t.c. The user might be accessing the Web document to procure information about a specific Web object, the remaining information in the Web object [2-6] becomes redundant specific to the user. If the size of Web documents is significantly large and the user information requirement is small fraction of the document, the user has to invest effort in locating the required information inside the document. It would be much more convenient if the user is provided with only the required Web object information located inside the Web documents. Web object search engines provide Web search facility through vertical search on Web objects. In this paper the main goal we considered is the objective information present in different documents is extracted and integrated into an object repository over which the Web object search facility is built.

RNAactDrug: a comprehensive database of RNAs associated with drug sensitivity from multi-omics data

Drug sensitivity has always been at the core of individualized cancer chemotherapy. However, we have been overwhelmed by large-scale pharmacogenomic data in the era of next-generation sequencing technology, which makes it increasingly challenging for researchers, especially those without bioinformatic experience, to perform data integration, exploration and analysis. To bridge this gap, we developed RNAactDrug, a comprehensive database of RNAs associated with drug sensitivity from multi-omics data, which allows users to explore drug sensitivity and RNA molecule associations directly. It provides association data between drug sensitivity and RNA molecules including mRNAs, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) at four molecular levels (expression, copy number variation, mutation and methylation) from integrated analysis of three large-scale pharmacogenomic databases (GDSC, CellMiner and CCLE). RNAactDrug currently stores more than 4 924 200 associations of RNA molecules and drug sensitivity at four molecular levels covering more than 19 770 mRNAs, 11 119 lncRNAs, 438 miRNAs and 4155 drugs. A user-friendly interface enriched with various browsing sections augmented with advance search facility for querying the database is offered for users retrieving. RNAactDrug provides a comprehensive resource for RNA molecules acting in drug sensitivity, and it could be used to prioritize drug sensitivity–related RNA molecules, further promoting the identification of clinically actionable biomarkers in drug sensitivity and drug development more cost-efficiently by making this knowledge accessible to both basic researchers and clinical practitioners.
