This document proposes a trust behavior-based recommender system for software usage. It outlines constructing a model of trust behavior by observing users' normal usage, problem reflection, and correlation behaviors. The system would generate recommendations based on correlating these trust behaviors across users. An evaluation of the system achieved personalized recommendations as a concrete indicator of interest similarity and preferences. Future work includes improving user acceptance and further performance evaluations using real data.

Effects of Option Characteristics and Underlying Stock on Option BetaDharma Bagoes Oka

Beta (β) is one of the risk management tools to capture the risk exposures of hedge-fund investments. As most of hedge funds today trade derivative securities, the research on the measurement of derivative beta is important. The aim of this paper is to examine the factors, which may have impacts on option beta in the United States market. My hypothesis is comprised into three main parts. First, I hypothesize that 5 variables (type of option, strike price, days to maturity, firm size and book to market ratio) have linear relationship with the option beta. Second, I hypothesize that the strength of linear relationship is varied by the type of the industry. Third, I hypothesize that the strength of linear relationship is also varied by these 5 types of variables itself. To begin the process, I use regression method to estimate the beta of underlying stock. Then, I estimate the option beta by multiplying the beta of underlying stock and the option elasticity. I then use regression method to test whether the 5 variables have linear relationship with option beta. I find that 3 variables (type of option, strike price and days to maturity) have the most significant linear relationship with option beta, while firm size has less significant linear relationship and book to market ratio have no significant linear relationship. Furthermore, using 2-way ANOVA, I test whether strength of linear relationship is varied by the type of the industry and the 5 types of variables. There is not enough evidence to infer that the strength of linear relationship between the 5 variables to option beta is varied by the type of the industry, instead, there is enough evidence to infer that the strength of linear relationship between the 5 variables to option beta is varied by the type of variables.

Mining of product reviews at aspect levelijfcstjournal
Â
Todayâs world is a world of Internet, almost all work can be done with the help of it, from simple mobile
phone recharge to biggest business deals can be done with the help of this technology. People spent their
most of the times on surfing on the Web; it becomes a new source of entertainment, education,
communication, shopping etc. Users not only use these websites but also give their feedback and
suggestions that will be useful for other users. In this way a large amount of reviews of users are collected
on the Web that needs to be explored, analyse and organized for better decision making. Opinion Mining or
Sentiment Analysis is a Natural Language Processing and Information Extraction task that identifies the
userâs views or opinions explained in the form of positive, negative or neutral comments and quotes
underlying the text. Aspect based opinion mining is one of the level of Opinion mining that determines the
aspect of the given reviews and classify the review for each feature. In this paper an aspect based opinion
mining system is proposed to classify the reviews as positive, negative and neutral for each feature.
Negation is also handled in the proposed system. Experimental results using reviews of products show the
effectiveness of the system.

Web User Opinion Analysis for Product Features Extraction and Opinion Summari...dannyijwest
Â
Selling the product through Web has become more popular because of online shopping. This enables
merchants to sell their products through Web and expects the customer to express their opinion through
online about the product which they have purchased. Due to this we find number of customer reviews on a
particular product, it varies from hundreds to thousands, for some product it is more than that. In order to
help the customer and the manufacture/merchant we propose a semantic based approach to mine different
product features and to find the opinion summarization about each of these extracted product features by
means of web user opinion expressed through the customer reviews using typed dependency relations.
A Critical Evaluation of Popular UX Frameworks Relevant to E-Health Appsrinzindorjej
Â
This research paper aims to evaluate the usability, accessibility, and effectiveness of the current User Experience (UX) frameworks relevant to mobile health apps, with a specific focus on the FitBit app. The selected UX frameworks for evaluation include Nielsen Norman Group's 10 Usability Heuristics, Don Norman's Three Levels of Design, and Human-Centered Design. A mixed-method approach, comprising both qualitative and quantitative analyses, was employed to evaluate these frameworks. The FitBit app was assessed based on the selected frameworks, and the obtained results were compared with existing literature and industry standards. The main subject of this study is the critical evaluation of popular UX frameworks in the context of e-health apps, with a specific emphasis on the FitBit app. The evaluation factors considered include usability, accessibility, and effectiveness. By utilizing the selected UX frameworks, the paper seeks to identify the strengths and limitations of each framework in evaluating e- health apps. The achieved results reveal that Nielsen Norman Group's 10 Usability Heuristics are valuable in identifying usability issues within the FitBit app. Don Norman's Three Levels of Design effectively evaluate the overall user experience, providing insights into the app's design quality. Human- Centered Design, on the other hand, offers a comprehensive and holistic approach to designing for the user, encompassing various aspects of the FitBit app. Through this research, a comprehensive understanding of the strengths and limitations of the evaluated UX frameworks in relation to e-health apps, specifically the FitBit app, is attained. The findings contribute to the existing literature on UX evaluation and provide insights for designers and developers to enhance the user experience of mobile health applications.

USING NLP APPROACH FOR ANALYZING CUSTOMER REVIEWScsandit
Â
The Web considers one of the main sources of customer opinions and reviews which they are represented in two formats; structured data (numeric ratings) and unstructured data (textual comments). Millions of textual comments about goods and services are posted on the web by customers and every day thousands are added, make it a big challenge to read and understand them to make them a useful structured data for customers and decision makers. Sentiment
analysis or Opinion mining is a popular technique for summarizing and analyzing those opinions and reviews. In this paper, we use natural language processing techniques to generate some rules to help us understand customer opinions and reviews (textual comments) written in the Arabic language for the purpose of understanding each one of them and then convert them to a structured data. We use adjectives as a key point to highlight important information in the text then we work around them to tag attributes that describe the subject of the reviews, and we associate them with their values (adjectives).

A Review on Sentimental Analysis of Application ReviewsIJMER
Â
As with rapid evolution of computer technology and smart phones mobile applications
become very important part of our life. It is very difficult for customers to keep track of different
applications reviews so sentimental analysis is used. Sentimental analysis is effective and efficient
evolution of customerâs opinion in real time. Sentimental analysis for applications review is performed
two approaches statistical model based approaches and Natural Language Processing (NLP) based
approaches to create rules. Two schemes used for analyzing the textual comments- aspect level
sentimental analysis analyses the text and provide a label on each aspect then scores on multiple
aspects are aggregated and result for reviews shown in graphs. Second scheme is document level
analyses which comprising of adjectives, adverbs and verbs and n-gram feature extraction. I have also
used our SentiWordNet scheme to compute the document-level sentiment for each movie reviewed
and compared the results with results obtained using Alchemy API. The sentiment profile of a movie is
also compared with the document-level sentiment result. The results obtained show that my scheme
produces a more accurate and focused sentiment profile than the simple document-level sentiment
analysis.

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).

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.
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
Â
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).
