Log4j is a simple, reliable, fast, and flexible login framework which is written in java. It is highly configurable through external configuration files at run time. We configure Log4j through configuration files which can be XML files, properties file, JSON file, etc. Log4j has been ported to languages like C, C++, Perl, Python, C#, etc. It is used for small to large scale projects in Selenium Automation. Why use Log4j? Log 4j is an open-source toolLog 4j is used for small and large scale projectsWith Log4j, it is possible to store the flow details in a file or database.Rather than using SOPL statements, we use log statements in the code to know the status of the project while executing.
Log4j main components: Loggers: It is used to log the information. Note: We can call the appender with any name in log4j properties. Layouts: It is used for formatting logging information in different styles. To handle logging activities the Logger class provides different methods. Root logger. Different Methodologies in Software Development Life Cycle - The overall objective of software design is to make sure that the stakeholders apprehend the design and verify that the project teams understand their needs and expectations clearly.
A software development life cycle focuses on producing the high quality software product to meet the stakeholders’ expectations. A life cycle is a chain of multiple steps that lead to the completion of a project. Over the years, various software development life cycles have been used and practiced in the industry. Software development life cycles are used every day in IT departments around the world. Data Aggregation in Tableau - H2kinfosys Blog. Aggregation is a calculation of some kind applied to the most granular level of data that helps to describe or summarize it in some way.
Tableau supports many aggregation types, such as: SumAverageCountCount DistinctMedianMinimumMaximumVarianceVariance of PopulationStandard DeviationStandard Deviation of PopulationAttributeDimension You can create aggregation dimensions and measures in Tableau. When you add measures to your view, an aggregation is applied by default to those measures. The type of Aggregation depends on the context of the view. Why Does Java make One Think Like a Programmer?

POS Tagging and Hidden Markov Model - H2kinfosys Blog. From elementary school, we were taught to identify the parts of speech in a sentence.
The fancy word for this process is called POS tagging. POS tagging may seem like an easy task but in reality, it can get really messy. In some situations, one word may have different meanings and by extension, different parts of speech, based on its context. Take a look at the sentences below The man wore a bow tie to the meeting.A bow and arrow were all the hunter needed to bring down the bear.Villagers are expected to bow at the sight of a royal one. In these three sentences, the word ‘bow’ has three different meanings and in fact, three different parts of speech.
To overcome this, machine learning models offer a more convenient way to POS tagging. “Some drivers desert their passengers when they get to the desert” In the statement above, the word ‘desert’ had two different POS based on its context. Output: Sure, it did. POS tagging is a required step in virtually all NLP applications. Markov Model. Best Python IDEs For Data Science - H2kinfosys Blog.
A Data Scientist is responsible for extracting, manipulating, pre-processing, and producing predictions out of data.
So, to do such tasks, he requires a comfortable environment to work with. In this article, we will discuss the best python IDEs utilized by Data Scientists to do their data tasks. We will comprehend the key highlights of the python IDEs, the benefits they give, and the examination of different data science tools. LOD Expressions in Tableau - H2kinfosys Blog. Tableau LOD (Level of Detail) expressions are used to find answers to questions that involve multiple levels of granularity in a single visualization.
With the help of LOD expressions, you can compute aggregations that are not at the detail level of visualization. You can also incorporate the aggregation values within the data visualizations in many ways and give more control to determine the granularity level in your computations. How to create LOD expressions? Step 1: Set up the Visualization Open the Tableau Desktop and add data source Sample-Superstore.Navigate to a new worksheet.From the Data pane, under Dimensions, drag the field Region to the Columns Shelf.From the Data pane, under Measures, drag the field Sales to the Rows Shelf.

Tokenization in NLP Tutorial - H2kinfosys Blog. Tokenization is the process of splitting a chunk of text, phrase, or sentence into smaller units called tokens.
The smaller units could be individual words or terms. Tokenization is a pivotal step for extracting information from textual data To build NLP driven systems, such as sentiment analysis, chatbot, language translation, or a voice assistant, patterns will need to be learned from a conversation. Tokens are used to learn patterns from a chunk of text. They are also used for other NLP operations such as stemming and lemmatization. Tokenization operations are performed using the tokenize module of NLTK’s library. Tokenization of Words The word_tokenize method is used for splitting a corpus into individual words.
Since machine learning algorithms require numeric data to learn from data and make predictions, it becomes critical to apply Tfidf_vectorizer or Count_vectoriser on the tokens. Big Data Interview Questions and Answers - H2kinfosys Blog. 1.
What does the term “Big Data” mean? Big Data is about complex and large datasets. Special tools and methods are used to perform operations on big data because a relational database cannot handle it. Big data processing helps companies to understand their business better. We can derive meaningful information from the data collected that is raw and unstructured. 2. They are Volume, Velocity, Variety, Veracity, Value. Database Testing using Selenium - H2kinfosys Blog. Testing your web applications using Browser is limited in Selenium Webdriver.
