Lexical Semantics, Semantic Similarity and Relevance for SEOKoray Tugberk GUBUR
Lexical semantics and relations between words include relations of superiority, inferiority, part, whole, opposition, and sameness between the meanings of words. The same word can be a meronymy, hyponym, or antonym of another word, depending on the word before or after it. The lexical relation value of the first word can affect the structure of the next word, affecting the context of the sentence and the Information Retrieval Score. Information Retrieval Score is the score that determines how much content is related to a query, how close the different variants of the related query are, and the structure processed by the search engine’s query processor to the relevant document. A higher information retrieval score represents better relevance and possible click satisfaction.
The problem with a semi-structured and distracting context for Information Retrieval Score is that, if a document is not configured for a single topic, the IR Score can be diluted by the two different contexts resulting in a relative rank lost to another textual document.
IR Score Dilution involves badly structured lexical relations, along with bad word proximity. The relevant words that complete each other within the meaning map should be used closely, within a paragraph or section of the document, to signal the context in a more clear way to increase the IR Score. A search engine can check whether the document contains the hyponym of the words within the query or not. A possible query prediction can be generated from the hypernyms of the query. A search engine can check only the anchor texts to see whether there is a word within the “hyponym distance” which represents the hyponym depth between two different words.
Lexical Relations can represent the semantic annotations for a document. A semantic annotation is a word that describes the document overall in terms of category and main context that carries the purpose of the document. A semantic annotation can contain the main entity of the document or a general concept for covering a broader meaning area (knowledge domain). Semantic Annotations can be generated with the lexical relations between words. A semantic annotation can be used to match the document to the query. Semantic annotations are factors for a better IR Score.
A search engine can generate phrase patterns from the lexical relationships between words within the queries or the documents. A phrase pattern contains sections that define a concept with qualifiers. Phrase patterns can contain a hyponym just after an adjective, or a hypernym with the antonym of the same adjective. Most of these connections and patterns are used within the Recurrent Neural Network (RNN) for the next word prediction. A phrase pattern helps a search engine to increase its confidence score for relating the document to the specific query, or the meaning of the query.
Natural Language Processing (NLP) is a field that combines computer science, linguistics, and machine learning to study how computers and humans communicate in natural language. The goal of NLP is for computers to be able to interpret and generate human language. This not only improves the efficiency of work done by humans but also helps in interacting with the machine. NLP bridges the gap of interaction between humans and electronic devices.
Natural Language Processing (NLP) is a subfield of artificial intelligence that deals with the interaction between computers and humans in natural language. It involves the use of computational techniques to process and analyze natural language data, such as text and speech, with the goal of understanding the meaning behind the language.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. 1. SENTENCE SEGMENTATION
• Sentence segmentation is the process of splitting a document of
text into individual sentences.
3. 2. TOKENIZATION
• Tokenization is the process of splitting a document into individual
words.
• Tokenization and sentence splitting usually go hand in hand.
• For example, Stanford’s CoreNLP expects tokenization to be
done before sentence segmentation.
4. 3. PART OF SPEECH TAGGING
• Part of speech (POS) tagging inspects your text and decides if the
individual words are nouns, adjectives, verbs, adverbs etc. There
are a lot of POS tags (over 35 according to this list on
StackOverflow).
• http://stackoverflow.com/a/1833718/7337349
5. 4. STEMMING
• Stemming is the process of getting the “root” from a word
• For example, the words organize, organized and organizing are
all derived from organize, and when you do a search for the
word organize, you would expect to also get the other forms of
the word since they represent the same idea.
• A very important thing to note (especially if you end up using
stemming in your NLP projects) is that the stem of a word does
not have to be and often isn’t a dictionary word.
• E.g the stem of the word “saw” is just “s”.
6. 5. LEMMATIZATION
• Lemmatization is similar to stemming in that it tries to get the
root of a word, except that it tries to regularize the word to end
up with a dictionary word.
• E.g. the lemma of the word “saw” is either “see” or “saw”
based on whether the token was a verb or a noun.
7. 6. NAMED ENTITY RECOGNITION
• Named Entity Recognition or NER is simply the process of
extracting nouns from your text.
• For example, using NER, you could automatically detect all the
occurrences of a brand name in a person’s Twitter feed.
8. 7. PARSE TREES
• Syntax or constituent
parse trees
• Is concerned with how
words combine to form
constituents of a
sentence
• Dependency parse tree
• Is concerned with the
relationship between the
words in a sentence
Source: http://www.nltk.org/book/ch08.html
9. 8. COREFERENCE RESOLUTION
• Coreference occurs when two or more expressions in a text refer
to the same person or thing.
• For example, in the sentence “Bill said he would come”, the
word “he” refers to Bill.
• Coreference resolution is the ability to resolve the co-reference
to find what it is referring to.
10. 9. POLARITY DETECTION
• This is a fancy term for deciding whether a piece of text conveys a
positive or a negative sentiment. Imagine if you are writing a
program for figuring out whether a tweet says something positive
or negative about a brand.
11. 10. INFORMATION EXTRACTION
• Information Extraction is the process of extracting facts (about
the world) from text information.
• For example, if you saw the sentence “Nigeria is a country in
Africa” you should be able to answer the question “India is a
country in ______”.
