Social media has risen as a powerful social link among people. It gives them an easy, unsupervised, rapid and flexible platform for sharing information with each other. It serves like a virtual environment where there is no direct or indirect executive power to dictate their opinions. They feel free to appreciate or criticize the actions of others. That is why social media posts carry true reflection of public feelings over any social event. This very nature of social media content makes it a valuable asset for research community to dig deeper and find meaningful concerns out of its huge chunks. This research work explores how people across different regions of Pakistan think about any social media topic. The research work proposed a model to extract spatial, topical and sentimental information of social media posts and combine them together to perform location-based sentiment mapping of the topics detected in social media. The study area has been restricted to Pakistan.The research work started with collection of tweets using streaming API of the Twitter. The information contained in a 3rd party dataset worldCities was used to filter out Pakistani tweets and perform indirect conversion of user profile location into geo-location, as geo-location was directly not available with tweets. Probabilistic topic model; Latent Dirichlet Allocation (LDA) was used to extract latent topics from the dataset. CRAN library was used for sentiment classification of the tweets into 3 classes: positive, negative and neutral. The processed dataset was uploaded to a persistent storage Google Drive and then imported into a web based interactive self-written Shiny Application to read geo-spatial, topical and sentimental information of the tweets from processed dataset and produce interactive geographical map. The interactive geographical map has also been supported by heatmap, scatter plots, bar graphs and pie charts in order to enhance visualization process. The novelty of this research work is its location-based visualization of the strength of public opinion on any emerging event or topic in Pakistan.

اپنی کتاب کا دیباچہ لکھنا توحالیؔ جیسے لوگوں کو جچتا ہے جو دیباچہ لکھیں تو تنقید کی پہلی کتاب وجود پا جائے۔میں تو عاجزانہ طور پر چند عروضی نکات پیش کرنا چاہتا ہوں۔میرا یہ دیباچہ سب کے لیے نہیں ہے۔ اس کی دو وجوہات ہیں۔ ایک تو عروضی بحث اس قدر گنجلک اور پیچیدہ ہوتی ہے کہ ہر کسی کو اس سے شغف نہیں ہوتا اور دوسرا جو لوگ عروض پہ دسترس رکھتے ہیںان کے لیے اس وضاحت کی ضرورت نہیں کیوں کہ وہ عروض پہ اس دیباچے سے بہت بہتر کتابیں پڑھ چکے ہیں۔ یہ دیباچہ فقط ان لوگوں کے لیے ہے جو شعر کہتے ہیں اور عروض میں بھی ٹانگ اڑاتے ہیں اورجب کسی شعر کی بحر سمجھ نہ آئے تو اسے بے وزن کہہ دیتے ہیں۔زیادہ تر ہندی بحر کے سلسلے میںان کا رویہ ایسا ہوتا ہے اوراگر ان کے سامنے کسی بڑے شاعر کا مصرع بہ طور نمونہ رکھ دیا جائے تو وہ اسے بھی بے وزن کہنے سے ذرا نہیں ہچکچاتے۔ فاع فاعلن یا فعَل فعولن ان کی سمجھ سے باہر ہو جاتا ہے۔ دراصل ایسے حضرات ہندی بحر کی چند معروف صورتوں کے سوا باقی صورتوں سے آشنا ہی نہیں۔
میرا یہ شعری مجموعہ ہندی بحر میںہی تخلیق ہوا ہے اور ہندی بحر میں خاصا تنوع پایا جاتا ہے۔ہمارے وہ لوگ جو عروض کو سرسری طور پر جانتے ہیں۔اس بحر کو سمجھنے میں ٹھوکر کھاتے ہیں۔وہ ہندی بحر کی چندمعروف صورتوں سے ہی واقف ہیں۔وہ بس اِسے ہی ہندی بحر سمجھتے ہیں مگر ہندی بحر کی متنوع صورتیں ہیں۔ان حضرات کے سامنے اگر کوئی مختلف صورت آ جائے تو وہ اسے سمجھنے سے قاصر رہتے ہیں کیوں کہ وہ ان صورتوں سے آشنا ہی نہیں اور وہ اسی ناآشنائی میں اس مصرعے کو بے وزن کہہ دیتے...

الروائع البلاغية للتذييل في النثر، والشعر

The Holy Qur’ᾱn is the Last book of Allᾱh and a great miracle of the Holy Prophet (SAW) the like of which could not be produced by any of all times. The Language of the Qur’ᾱn is Arabic known for its brevity and eloquence. The reality of the Arabic Language can be summoned by acquaintance with “Tadhīīl” and eloquence. Neology is a part of eloquence and communication is a component of neology, encompassing many discernments and points of wisdom. The same is corroborated in galore in poetry along with Qur’ᾱn and Hadîth. This illustrates the text and defines the aim and purpose. The purpose aimed at embraces eneomism and eulogy, didactics and exhortations and felicitations. The dictionary and literary meaning of “Tadhīīl”, types of “Tadhīīl” and use of places has been stated. The examples of Qur’ᾱn, prose and poem have also been given, Where the word “Tadhīīl” has been used.

Multiple Media Information Search Framework

Nowadays, together with the increasing spread of online multimedia information, user’s information needs have become more complex. To fulfill information needs, users mainly rely on web search engines. The traditional ways of presenting search results are often unsatisfactory. Web search engines usually provide the search of multimedia documents that encapsulates different media objects. A web page is a most known example of a multimedia document. Web search approaches enable vertical search of media objects that belongs to different media formats. In vertical web search, the retrieval granules are media objects presented by employing non-blended integration mechanisms. The presentation of search results is also linear. In recent years, aggregated search approaches have emerged to satisfy user’s complex information needs. Aggregated search approaches retrieve, merge, rank, and present results to the users from separate vertical media sources. The search results are possibly integrated via blended, partial-blended, or non-blended integration mechanisms; however, the presentation is still linear. In aggregated search, the retrieved media objects have semantic and multimodal similarity relationships that are not exploited to support user’s exploration activities. Over the years, aggregated search tools have been investigated by the researchers. Aggregated search tools usually do not consider the multimodal nature of media objects in search results exploration activities. They address the exploration of only specific media types or a subset of them. Aggregated search tools enable only document-to-document browsing. Furthermore, retrieval granule are either media objects or multimedia documents. This thesis aims to address the issues that are related to the results exploration in aggregated search. The thesis focuses to provide a novel mechanism to explore results in aggregated search. The main objective is to give users a possibility to dynamically visualize and explore a search result space built over a repository of multimedia documents and their connected media objects in an integrated way. To do this a novel multiple media information search framework is proposed. Particularly, search framework initiates a search result space over the retrieved multimedia documents and their connected media objects. The search result space treats multimedia documents and media objects as retrieval granules. The search result space connects multimedia documents and media objects and media objects with each other via part-of and multimodal (textual, acoustic, and visual) similarity relationships respectively. The search result space is further exploited in results exploration activities. The search framework formally defines a set of components to provide an exploration of results in aggregated search of multiple media information. The search framework is further represented as an architecture that encapsulates framework components in data, search, data model, viii and interface layers. Data layer retrieves multimedia documents, media objects, and features associated with media objects. Search layer provides fielded search of media objects connected with the multimedia documents. Results representation layer initiates a search result space over multimedia documents and their connected media objects retrieved in aggregated search. Interface layer enables expression of multiple media based information needs and exploration of the search results. We realized the framework by implementing a full-fledged multiple media information search tool mainly to provide nonlinear interaction with the search results via full-blended integration, browsing, and visualization in an integrated way. The search tool instantiates a search result space via a particular graph data model on a publically available dataset of multimedia documents and their connected media objects. The search tool provides search results exploration by giving a results exploration mechanism and supporting various types of search tasks via particular results exploration interface components. We evaluated blended integration, browsing, and the connected search results exploration. We considered correctness and reachability factors in the effectiveness evaluation of blended integration and browsing respectively. Blended integration and browsing are compared further with the optimally ranked representation of search results, and they give satisfactory results. The effectiveness of search results exploration mechanism, search task support, and search interface components evaluated via task and scenario-based usability tests. In particular, we employed successful task completion, time-on-task, subjective measures of usability in supported search tasks, and overall user recommendations to evaluate results exploration mechanism. We tested the usability of lookup and exploratory search tasks via scenario-based evaluation. Furthermore, we conducted frequency usage, an interface component, and search results multi-representation analysis to highlight the usability of search interface components. The usability tests revealed that most users completed search task in given time constraints; search interface provides satisfactory results in subjective measures; users are satisfied with the search results exploration mechanism. The search interface supports lookup and exploratory search tasks to interact with the results. The users mostly spent time to interact with results presented via the linear list and browseable grid-based representation; however, users prefer all types of interactions given in the search interface to explore the results. Along with that, they like the browsing of multiple media information via grid and graph-based representations. Our framework provides nonlinear, multimodal, and unified exploration of results in multiple media information aggregated search in a usable way.
