Garbage in, garbage out. You don’t have to be an ML expert to have heard this phrase. Models uncover patterns in the data, so when the data is broken, they develop broken behavior. This is why researchers allocate significant resources towards curating datasets. However, despite best efforts, it is nearly impossible to collect perfectly clean data, especially at the scale demanded by deep learning.
This article discusses popular natural language datasets that turned out to disobey fundamental principles of machine learning and data science, despite being produced by experts in the field. Some of these flaws were exposed and quantified years after the publication and intense usage of the datasets. This is to show that data collection and validation are arduous processes. Here are some of their main impediments:
ML practitioners split their data three-ways: there’s a _training set _for actual learning, a _validation set _for hyperparameter tuning, and an _evaluation set _for measuring the final quality of the model. It is common knowledge that these sets should be mostly disjunct. When evaluating on training data, you are measuring the model’s capacity to memorize rather than its ability to recognize patterns and apply them in new contexts.
This guideline sounds straightforward to apply, yet Lewis et al.  show in a 2020 paper that **the most popular open-domain question answering datasets (open-QA) have a significant overlap between their training and evaluation sets. **Their analysis includes WebQuestions, TriviaQA and Open Natural Questions — datasets created by reputable institutions and heavily used as QA benchmarks.

According to a recent study, call centre agents’ spend approximately 82 percent of their total time looking at step-by-step guides, customer data, and knowledge base articles.
Traditionally, dialogue state tracking (DST) has served as a way to determine what a caller wants at a given point in a conversation. Unfortunately, these aspects are not accounted for in popular DST benchmarks. DST is the core part of a spoken dialogue system. It estimates the beliefs of possible user’s goals at every dialogue turn.
To reduce the burden on call centre agents and improve the SOTA of task-oriented dialogue systems, AI-powered customer service company ASAPP recently launched an action-based conversations dataset (ABCD). The dataset is designed to help develop task-oriented dialogue systems for customer service applications. ABCD consists of a fully labelled dataset with over 10,000 human dialogues containing 55 distinct user intents requiring sequences of actions constrained by company policies to accomplish tasks.
The dataset is currently available on GitHub.

Textual entailment is a technique in natural language processing that endeavors to perceive whether one sentence can be inferred from another sentence. A pair of sentences are categorized into one of three categories: positive or negative or neutral. The positive category happens when the main sentence is used to demonstrate that a subsequent sentence is valid. Negative entailment or contradiction occurs when the primary sentence can be utilized to invalidate the subsequent sentence. Finally, if the two sentences have no relationship, they are considered to have a neutral entailment.
Textual entailment is valuable in some of the applications. For example, it is used in question-answering systems to verify an answer from stored data. It may also be used to remove sentences that don’t have new information.

C may be a middle-level programing language developed by Dennis Ritchie during the first 1970s while performing at AT&T Bell Labs within the USA. the target of its development was within the context of the re-design of the UNIX OS to enable it to be used on multiple computers.
Earlier the language B was now used for improving the UNIX. Being an application-oriented language, B allowed a much faster production of code than in programming language. Still, B suffered from drawbacks because it didn’t understand data-types and didn’t provide the utilization of “structures”.
These drawbacks became the drive for Ritchie for the development of a replacement programing language called C. He kept most of the language B’s syntax and added data-types and lots of other required changes. Eventually, C was developed during 1971-73, containing both high-level functionality and therefore the detailed features required to program an OS. Hence, many of the UNIX components including the UNIX kernel itself were eventually rewritten in C.
Benefits of C language
As a middle-level language, C combines the features of both high-level and low-level languages. It is often used for low-level programmings, like scripting for it also supports functions of high-level C programming languages, like scripting for software applications, etc.
C may be a structured programing language that allows a posh program to be broken into simpler programs called functions. It also allows free movement of knowledge across these functions.
Various features of C including direct access to machine level hardware APIs, the presence of C compilers, deterministic resource use, and dynamic memory allocation make C language an optimum choice for scripting applications and drivers of embedded systems.
C language is case-sensitive which suggests lowercase and uppercase letters are treated differently.
C is very portable and is employed for scripting system applications which form a serious a part of Windows, UNIX, and Linux OS.
C may be a general-purpose programing language and may efficiently work on enterprise applications, games, graphics, and applications requiring calculations, etc.
C language features a rich library that provides a variety of built-in functions. It also offers dynamic memory allocation.
C implements algorithms and data structures swiftly, facilitating faster computations in programs. This has enabled the utilization of C in applications requiring higher degrees of calculations like MATLAB and Mathematica.
Riding on these advantages, C became dominant and spread quickly beyond Bell Labs replacing many well-known languages of that point, like ALGOL, B, PL/I, FORTRAN, etc. C language has become available on a really wide selection of platforms, from embedded microcontrollers to supercomputers.

Initial setup costs remain a barrier to market growth, as well as a lack of skilled professionals to implement NLP.
The natural language processing market, which includes machine translation, information extraction, summarization, text classification and sentiment analysis, is expected to reach a $41 billion valuation by 2025.
An increase in demand for analyzing conversations and social media, alongside other customer experience enhancements, are considered key drivers for NLP, according to Adroit Market Research.
