Quantification of Portrayal Concepts using tf-idf Weightingijistjournal
Term frequencies and inverse document frequencies have been successfully applied in determining
weighting for document rankings. However these have been more successful in text mining and in
extraction techniques used in the web. Concept mining has become increasingly popular in the research
and application areas of Computer Science. This paper attempts to demonstrate the limited usage of term
frequency and inverse document frequency for the application of weighting calculations for ranking
documents that are based on concept quantifications. The case study considered for experiment in this
paper, is based on concept terms of David Merrill’s First Principles of Instruction (FPI). Merrill’s FPI
applies cognitive structures explicitly for analyzing instructional materials. Therefore it is justified that the
terms categorized under each cognitive structure (or portrayal) of FPI can be taken as respective concept
of that portrayal. As question papers are representative of cognitive structures in a more clear and logical
way, four question papers on ‘C Language’ have been considered for the experimental study, that are
detailed in this paper. Manual method has been adopted for the computation of quantities of portrayals in
selected documents for the purpose of comparative study. As manual method is accurate, the values
(results) are considered as benchmark values. These benchmark values are considered for comparing with
normalized term frequencies that are derived (experimented) from automated extractions from the same
selected documents. The study is however limited to four documents only. Conclusions are drawn from this
experimental study, which will be of immense use to concept mining researchers as well as for instructional
designers.

Opinion Mining Techniques for Non-English Languages: An OverviewCSCJournals
The amount of user-generated data on web is increasing day by day giving rise to necessity of automatic tools to analyze huge data and extract useful information from it. Opinion Mining is an emerging area of research concerning with extracting and analyzing opinions expressed in texts. It is a language and domain dependent task having number of applications like recommender systems, review analysis, marketing systems, etc. Early research in the field of opinion mining has concentrated on English language. Many opinion mining tools and linguistic resources have been built for English language. Availability of information in regional languages has motivated researchers to develop tools and resources for non-English languages. In this paper we present a survey on the opinion mining research for non-English languages.
Scholars’ Perceptions of Relevance in Bibliography-Based People Recommender S...Ekaterina Olshannikova
Collaboration and social networking are increasingly important for academics, yet identifying relevant collaborators requires remarkable effort. While there are various networking services optimized for seeking similarities between the users, the scholarly motive of producing new knowledge calls for assistance in identifying people with complementary qualities. However, there is little empirical understanding of how academics perceive relevance, complementarity, and diversity of individuals in their profession and how these concepts can be optimally embedded in social matching systems. This paper aims to support the development of diversity-enhancing people recommender systems by exploring senior researchers’ perceptions of recommended other scholars at different levels on a similar–different continuum. To conduct the study, we built a recommender system based on topic modeling of scholars’ publications in the DBLP computer science bibliography. A study of 18 senior researchers comprised a controlled experiment and semi-structured interviewing, focusing on their subjective perceptions regarding relevance, similarity, and familiarity of the given recommendations, as well as participants’ readiness to interact with the recommended people. The study implies that the homophily bias (behavioral tendency to select similar others) is strong despite the recognized need for complementarity. While the experiment indicated consistent and significant differences between the perceived relevance of most similar vs. other levels, the interview results imply that the evaluation of the relevance of people recommendations is complex and multifaceted. Despite the inherent bias in selection, the participants could identify highly interesting collaboration opportunities on all levels of similarity.

Statistical Methods in Qualitative Research
Statistical Method
What is measured by this method
Circumstances for Use
Examples of use in Research Studies
Qualitative Content Analysis
Analyzes narrative data, and in-depth interviews. Can evaluate large volumes of data with intent to identify recurring themes and patterns. Attempts to break down elements of data into clusters. May be concurrent or sequential (Polit &Beck, 2017).
Good method for evaluating personal histories, perspectives, experiences. Best method for studying personal, sensitive situations (Sauro, 2015).
Examples of this methodology include evaluation of the experience of a rape victim, what it feels like to have an abortion, how it feels to have lived through a disaster.
Ethnographic analysis
Evaluates cultural phenomena, patterns, perspectives. Requires “participant observer” technique. No preconceived hypothesis. May take months or years to complete. Maps and flowcharts are tools to help illustrate findings (Polit & Beck, 2017).
Method to “acquire a deep understanding of the culture being studied” (Polit & Beck, 2017 p. 538).
An example of ethnographic analysis could include a research study with ethnographers integrating with Native Americans living on a reservation while observing everyday life seeking to extrapolate overlying cultural issues.
Phenomenologic Analysis
Attempts to understand the essence of experiencing a particular phenomenon by observation, interviews, and outside research. Descriptive analysis
Method for understanding individual perspectives of experiencing a certain phenomenon. Seeks to extrapolate commonalities and themes among subjects (Sauro, 2015).
Conducting interviews with persons who have experienced hallucinations, with the intent to understand their perspective and experience of the phenomenon, is an example of this method of research.
Grounded Theory Analysis
Aim is to provide theories and explanations for phenomena based on previously coded information Uses interviews and previous accepted research. Unlike Qualitative content analysis, which seeks to break down information, Grounded theory strives to put information back together (Polit & Beck, 2017).
Method for development of theories, Could be used meta-analyses or systematic reviews.
An example of a grounded theory analysis is” Beck’s (2002) model of mothering twins” as cited in Polit & Beck (2017).
Focus Group Analysis
Analyzes group data in relation to a specific topic. Group interviews, recordings, and field notes .are instruments for conducting this type of research.
May be used for evaluation of a potential survey too ...
Marketing has never been more interesting than now. The Internet and other new digital technologies are not only transforming the practice of marketing but also the way we think about it (Wymbs 2011). The main benefit of marketing automation is that it can help businesses grow sales and increase brand awareness by maximizing their email contact lists, streamlining processes for lead generation with automated forms or emails, as well as executing personalized campaigns based on information about a prospect's needs. Today, consumers have more choices, more services, more media, more messages, and more digital conversations than ever. Digital-driven changes are not only affecting private consumer’s behavior

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
