This document presents a framework for automatically generating entity-relationship (ER) diagrams from natural language text input. It involves five main modules: 1) text preprocessing and summary generation, 2) translating the summary to a Semantic Business Vocabulary and Rules (SBVR) format, 3) part-of-speech tagging, 4) extracting ER diagram requirements by identifying entities, relationships, and attributes, and 5) generating an XMI file that can be imported into a UML modeling tool to visualize the generated ER diagram. Keywords are extracted from the input text using term frequency, and sentences are scored and selected for the summary based on important keywords and nouns. The framework aims to reduce the complexity of manually creating ER diagrams by
Distributed Graphical User Interfaces to Class Diagram: Reverse Engineering A...ijseajournal
The graphical user interfaces of software programs are used by researchers in the soft-ware engineering
field to measure functionality, usability, durability, accessibility, and performance. This paper describes a
reverse engineering approach to transform the cap-tured images of the distributed GUIs into class
diagram. The processed distributed GUIs come from different and separate client computers. From the
distributed GUIs, the inter-faces are captured as images, attributes and functions are extracted and
processed through pattern recognitions mechanism to be stored into several temporary tables
corresponding to each client’s graphical user interface. These tables will be analyzed and processed into
one integrated normalized table eliminating any attribute redundancies. Further, the normalized the one
integrated table is to create a class diagram.
Formalization & data abstraction during use case modeling in object oriented ...csandit
In object oriented analysis and design, use cases represent the things of value that the system
performs for its actors in UML and unified process. Use cases are not functions or features.
They allow us to get behavioral abstraction of the system to be. The purpose of the behavioral
abstraction is to get to the heart of what a system must do, we must first focus on who (or what)
will use it, or be used by it. After we do this, we look at what the system must do for those users
in order to do something useful. That is what exactly we expect from the use cases as the
behavioral abstraction. Apart from this fact use cases are the poor candidates for the data
abstraction. Rather the do not have data abstraction. The main reason is it shows or describes
the sequence of events or actions performed by the actor or use case, it does not take data in to
account. As we know in earlier stages of the development we believe in ‘what’ rather than
‘how’. ‘What’ does not need to include data whereas ‘how’ depicts the data. As use case moves
around ‘what’ only we are not able to extract the data. So in order to incorporate data in use
cases one must feel the need of data at the initial stages of the development. We have developed
the technique to integrate data in to the uses cases. This paper is regarding our investigations
to take care of data during early stages of the software development. The collected abstraction
of data helps in the analysis and then assist in forming the attributes of the candidate classes.
This makes sure that we will not miss any attribute that is required in the abstracted behavior
using use cases. Formalization adds to the accuracy of the data abstraction. We have
investigated object constraint language to perform better data abstraction during analysis &
design in unified paradigm. In this paper we have presented our research regarding early stage
data abstraction and its formalization.

FEATURES MATCHING USING NATURAL LANGUAGE PROCESSINGIJCI JOURNAL
The feature matching is a basic step in matching different datasets. This article proposes shows a new hybrid model of a pretrained Natural Language Processing (NLP) based model called BERT used in parallel with a statistical model based on Jaccard similarity to measure the similarity between list of features from two different datasets. This reduces the time required to search for correlations or manually match each feature from one dataset to another.
Chunking means splitting the sentences into tokens and then grouping them in a meaningful way. When it comes to high-performance chunking systems, transformer models have proved to be the state of the art benchmarks. To perform chunking as a task it requires a large-scale high quality annotated corpus where each token is attached with a particular tag similar as that of Named Entity Recognition Tasks. Later these tags are used in conjunction with pointer frameworks to find the final chunk. To solve this for a specific domain problem, it becomes a highly costly affair in terms of time and resources to manually annotate and produce a large-high-quality training set. When the domain is specific and diverse, then cold starting becomes even more difficult because of the expected large number of manually annotated queries to cover all aspects. To overcome the problem, we applied a grammar-based text generation mechanism where instead of annotating a sentence we annotate using grammar templates. We defined various templates corresponding to different grammar rules. To create a sentence we used these templates along with the rules where symbol or terminal values were chosen from the domain data catalog. It helped us to create a large number of annotated queries. These annotated queries were used for training the machine learning model using an ensemble transformer-based deep neural network model [24.] We found that grammar-based annotation was useful to solve domain-based chunks in input query sentences without any manual annotation where it was found to achieve a classification F1 score of 96.97% in classifying the tokens for the out of template queries.

Conceptual Similarity Measurement Algorithm For Domain Specific OntologyZac Darcy
This paper presents the similarity measurement algorithm for domain specific terms collected in the
ontology based data integration system. This similarity measurement algorithm can be used in ontology
mapping and query service of ontology based data integration system. In this paper, we focus on the web
query service to apply this proposed algorithm. Concepts similarity is important for web query service
because the words in user input query are not same wholly with the concepts in ontology. So, we need to
extract the possible concepts that are match or related to the input words with the help of machine readable
dictionary WordNet. Sometimes, we use the generated mapping rules in query generation procedure for
some words that cannot be confirmed the similarity of these words by WordNet. We prove the effect of this
algorithm with two degree semantic result of web mining by generating the concepts results obtained form
the input query.

measure in particular is very important in the current scenario
due to the huge demand for natural language processing based
applications such as chatbots and information retrieval systems
such as knowledge base based FAQ systems. Current approaches
generally use similarity measures which does not use the context
sensitive relationships between the words. This leads to erroneous
similarity predictions and is not of much use in real life
applications. This work proposes a novel approach that gives an
accurate relatedness measure of any two words in a sentence by
taking their context into consideration. This context correction
results in a more accurate similarity prediction which results in
higher accuracy of information retrieval systems.

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).

Abstract:One of the procedures for obtaining the better understanding of the system by splitting the large
system into smaller parts, this procedure is termed as analysis. Manually creating softwareartifacts and
building UML models from natural language is a complex job. We represent diagrammatically structure of data
by ER diagram. This paper represents the use of heuristics picked up from the syntactic and semantic learning
for the automatic formation of database plan, which leads us to the identification and methodology to generate
Entity-Relationship(ER) through NLP.
The use of both syntactic and semantic heuristics is used as the system to obtain the critical ER parts,
components, qualities and associations from the specifications. In this method, we take English as input from the
client and our framework at first create summary of that few paragraphs utilizing code quantityprinciple. The
resultant summary is utilized in our automatic ER chart generation framework. Atlast a XMI record is made.
This file can be pictured in any of the UML modeling tools. Experimental Results on the usage of the semantic
heuristics demonstrate that these may help to further upgrade the outcomes in the modified differentiation of the
ER segments.
Keywords: Entity-Relationship Model,E-R Diagram, Data Modeling, XML, POS, Tokenization, NLP.
I. Introduction
AnEntity-Relationship model is a purposeful system for representing and describing a business process.
The strategy is shown as parts that are associated with each other by relationshipswhich articulate the conditions
and requirements amongthose, for example, one fusing may be differentiated with zero or more apartments, yet
one apartment must be put in one building. Entities may have distinct properties which portray them.
Diagramsgenerated to identify with these elements, attributes, and connections graphically are called
entityrelationship graphs. An E-R model is ordinarily actualized as a database. By virtue of a social database,
which stores data in tables, every column of every one table addresses one event of an entity. Some data fields
in these tables point to documents in distinct tables, such pointers address the relationship.
The natural language English has various ambiguities. The most remarkable among them is that diverse
individuals have particular interpretations of the same statement. These ambiguities make an issue in manual
generation of E-R chart. E-R frameworks are fundamental at the present time programming progression as
mistakes in the ER diagram can get reflected in the last item. Subsequently it is fundamental to make a correct
ER graph created at this stage can be difficult to modify later on. Analyzing requirements and creating the item
curious to assemble an ER graph is a confounded task. It is obliged to regularly create the ERD of a structure
with minimum human associations. A robotized tool can be created which will remove the appreciativedata to
create programming remainder which will be further utilized to build up the ER diagram of the given English
paragraphs.
Examination is a basic stage in development of software. The UML models gatheredduring the
examination stage help in the complete process of software development. This paper proposes a framework for
generating ER Diagram from the created summary i.e. communicated in English language. Initially a client
necessity is to enter the input paragraphs. Theseinput paragraphsare changed over into transitional semi-formal
representation termed as semantics vocabulary and rules. At this point synopsis gets changed over into
transitional semi-formal representation called as Semantics Vocabulary and rules. The Semantics Vocabulary
Rules is an approved standard of the Group of Object Management. Database setup is a methodology of making
a consistent data model for a specific database. Entity relationship showing, which is an irregular state sensible
model planned to empower database outline, can beoverwhelming undertaking to both understudies and
fashioners alike in light of the fact that of its extraordinary nature and subtle element. Much research has
attempted to apply natural language generating in removing data from requirements points of interest with the
plan databases.
Regardless, focus on the improvement and usage of heuristics to help the improvement of sensible
databases from natural language has been uncommon. The SBVR (Semantic Business vocabulary and Rule)
2. NLP for Automated Conceptual Data Modeling
DOI: 10.9790/0661-18110108 www.iosrjournals.org 2 | Page
characterizes the vocabulary and rules for reporting the semantics of business vocabularies, business actualities
and business rules. The SBVR representation of the issue explanation is given to the POS (Part of discourse)
labeling stage where every statement is labeled with the suitable parts of discourse. This labeled record is given
to the occasion extraction stage where occasions are separated Events are Entity sort, Substance, Relationship
sort, Attribute sort, Attribute for Entity, Property for relationship. The removed occasions are mapped to the
components of the ER graph. At last a XMI i.e. nothing however XML Metadata Interchange document is
created which can be foreign made in any of the UML demonstrating tool to see the created ER chart.
II. Literature Survey
For generating the entity relationships there is need of entity and relationship in paragraph. For that in
this paper framework uses code quality guideline [1] for generating the summary. Programmed contented
summarization by brushing the Information Retrieval (IR) methodologies with the semantic models code sum,
memory and respect for get the significantsentences [2]. In our procedure we are refining the most basic
information from the source to get the genuineconcept in the dense structure. We have initially emptied the
repetition of the information and we have paced the sentences concentrated around the linguistic principles code
quantity, memory and consideration.
The methodology begins by analyzing a plain entered substance data containing a necessities
determination of a database problem in English. Therefore, a parser is obliged to parse the English sentences to
get their grammatical feature [2] marks before further taking care. Grammatical feature marking selects each one
saying in a data sentence it’s fitting grammatical form, for example, verb and determiner to mirror the
announcement's syntactic class. Grammatical feature short structure and its importance. Grammatical feature
labeling is only discovering each word placein sentence. In Natural language processing POS is imperative for
substantially more processing.
The work like DMG [3] gives a premise to the improvement of novel heuristics connected in ER-
Converter. DMG is a rule based diagram instrument i.e. outline tool which keeps up standards and heuristics in a
couple of information bases. A parsing algorithm which becomes acquainted with a language structure and a
vocabulary is planned to meet the essentials of the tools. During the parsing stage, the sentence is parsed by
recuperating key information from the semantic utilization, spoken to by syntactic standards and the lexicon.
The parsing results are changed further on by rules and heuristics which set up a relationship in the middle
semantic and arrangement learning. The DMG needs to connect with the customer if an announcement does not
exist in the vocabulary or the information of the mapping rules is indistinct. The linguistic structures are then
changed by heuristics into EER ideas. Regardless of the way that DMG proposed incalculable to be used as a
part of the change from regular dialect to EER models, the device has not yet been made into a commonsense
system.
In [4], much workhas tried to apply trademark dialect in differentiating data fromnecessities particulars
or dialog sessions with makers with the arrangement to plan databases. Dialog tools [3] is a data based device
associated with the German language for making anoutline framework of an Enhanced Entity-Relationship
(EER) model. This instrument is a bit of a greater database layout structure known as RADD which involves
distinct portions that structure a complex device.
E-R generator [5] is a substitute rule based structure that makes E-R models from natural language
determinations. The E-R generator contains two sorts of rules: specific standards associated with semantics of a
couple of words in sentenceand bland chooses that perceive substances and associations on the reason of the
smart sign of the sentence and on the reason of the components and associations being worked on. The learning
representation structures are building by a naturallanguageunderstandersystem which uses a semantic
interpretation approach. There are circumstances in which the system needs help from the customer with a
particular final objective to determine ambiguities, for example, the association of characteristics and deciding
anaphoric references.
In [6], a methodology of making ER segments characteristically from natural language particulars
using heuristics. Semantic heuristics are proposed to be utilized in conjunction with the syntactic heuristics to
upgrade the accuracy of the outcomes in making the ER parts from regular naturallanguage particulars. The
dedication made can be joined in zones, for example, some bit of the space model of a smart coaching structure,
proposed to help in the learning and training of databases and different applications of NLP for database plan.
In [7], a novel procedure of making an interpretation of natural language to SBVR business standards.
Regularly, business standard master needs to physically make a several business administers in a Natural
language (NL) and after that physically translate NL determination of each and every one of fundamentals in a
particular principle, for instance, SBVR, as required. This paper proposes an automated methodology that
characteristically translates the Natural lingo (NL) (i.e. English) particular of business rules to SBVR Semantic
Business Vocabulary and Rules standards. These methodologies use a rule based count for healthy semantic

investigation of English, and make SBVR standards. The fundamental methods that we are taking after are
tokenization, sentence splitting, parts of speech tagging and morphological investigation.
In [8], Automatic evaluation of sequence diagram they analyze two regions of examination. To begin
with, they review the way of the errors made by students when drawing sequence diagram and how that
information has affected the setup of a learning device. Second, they discuss the adequacy of his modified
checking procedure when joined with sequence diagrams. They close with a discussion of how the two strands
of this research can be joined to give anextensive alteration device to help students construct right sequence
diagrams.
In [9], they uncover a procedure to the programmedinterpretation ofdiagram assembled arranged in
light of a 5-stage framework. The paper depicts procedure to subsequently assessing diagramassembled outlines
and reports in light of a couple of investigations into the programmed inspecting of understudy graphs. This
paper described both proposed framework general procedure for examining at detached diagrams and how they
have used our advancement as a part of particular in set of softwaretools planned for learning and assessing
graph based charts. Customary samples of graph based diagrams are entity relationship diagrams, Unified
Displaying Language charts, natural flow diagrams and chemical structure diagrams. In the work discussed here,
they have used entity relationship diagram as a model of graph based charts.
III. Proposed System
The representation of the proposed systemis as follows:
3.1System Architecture
The systemis distributed in to five modules. The brief description of these modules is as follows:
Figure.1 SystemArchitecture
1. Module 1: Initially we discussed about the input providing to the system. The natural language textual
information is taken as the input to the system. The information contains the few paragraphs.
Pre-processing: before generation of summary we need to do some process on input text for further
process. This process includes tokenization, sentence separation, stop words removing, Stemming, part
of speech tagging.
Achieve Dissimilarity: If two sentence having same meaning (may be one sentence is sub sentence of
other sentence) then keep one of them.
Keywords extraction: Find out most frequent words for sentence ranking
Sentence scoring: Based on important keyword and noun (CQP) words contain in sentence assign
weight to each sentence.
Summary generation: Based on weight of each sentence select top weighted sentences as summary of
all paragraphs or documents.
2. Module 2: In this module natural languages specification is translated to SBVR [7] business rules.
SBVR is a short type of “Semantic Business Vocabulary and Rules” [7]. To decrease the gap between
business expert and IT persons, Semantic Vocabulary and Rules has been presented by Object
Administration Group (OMG). This is better method for catching the business necessities in common
language. Like structure it is straightforward for people. Because of its higher request of rationale

establishment it is exceptionally easy to machine process. All particular representations and meaning of
realities and ideas utilized by an association as a part of course of business are considered as
vocabulary. In SBVR a formal presentation under the business impact are considered as rules which are
utilized to express the operation of specific business element under particular conditions. Output of this
module is summary in semantic vocabulary rule format.
3. Module 3: Part of Speech Tagging to each word. In this module the words in a sentence are divided
and labeled with specific documentations like NNP for Proper person noun, place or thing, NP for noun
phrase, VP for verb phrase, and so on. A parse tree for each one sentence is likewise produced. We
utilize this methodology for producing parse tree for a sentence which will be given as input.
4. Module 4: Extract ER diagram requirement. For ER diagram construction need to find out
relationship, entity and attributes. Common noun as Entity type, Proper noun as Entity, Transitive verb
as Relationship Type, Intransitive verb as Attribute type, Adjective as Attribute for entity, adverb as
attribute for relationship. Save this output in XMI file.
5. Module 5: Use star UML modeling tool. XMI file generated by module 4 is imported in this tool.
Then the imported file is opened, which is our expected output i.e. E-R diagram

3.4 Mathematical Model
3.4.1 Keywords Extraction
We need to find out important keywords or terms, for thisLet,
S= s1, s2 ...sn,
Where,
S is set of all user input sentences
Keywords (W) is defined as,
W= w1, w2, .....,wk
Where,
wk is k number of keywords,
Each keyword weight is calculated by using
Tfi,j= Σsi,j
Where,
Sij is the occurrence of keyword j in sentences i
If 𝑡𝑓 𝑗 > 𝑡𝑟𝑒𝑠𝑜𝑙𝑑
Add in final keyword List
𝐾𝑊 𝑆𝑖.𝑘 =
𝐾𝑦𝑤𝑜𝑟𝑑𝑐𝑜𝑢𝑛𝑡 𝑆 𝑖.𝑘
𝑙𝑒𝑛𝑔𝑡 𝑆 𝑖.𝑘
………….…….……1
Where
𝐾𝑦𝑤𝑜𝑟𝑑𝑐𝑜𝑢𝑛𝑡 is total no of occurrence of final keyword i in sentence Sk,
Length is Total no of words in sentence Sk,
i is sentence number,
k is document number.(In our systemk=1).
Proper Noun Feature:
In general the sentence that contains more proper nouns is an important one and it isMost probably
included in the document summary.
Proper nouns (PN) in the sentence is calculated by
𝑃𝑁 𝑆𝑖.𝑘 =
𝑃𝑁𝑐𝑜𝑢𝑛𝑡 𝑆 𝑖.𝑘
𝑙𝑒𝑛𝑔𝑡 𝑆 𝑖 .𝑘
………….…….……2
Where
PNCount is total no of nouns in sentence Si:k,
Length is Total no of words in sentence Si;k,
i is sentence number,
k is document number.(In our systemk=1).
IV. Experimental Results And Discussion
For Study of "Automatic ER diagramcreation" framework we tested distincttextdocumentsone after
another. Proposed framework producesvery good summary of every documents and after that it produces XMI
file of every document. Framework uses Star UML modeling tool for perspective ER outline. Every report XMI
record is open in this setup and result demonstrates that ER diagram is produced exceptionally well.
At last as per the outcomes acquired by above test on distinct records, we can say that our framework gives
client fulfillment, well rundown and programmed create ER diagram.

1. Input file
Following screenshot shows the input file which takes the input as paragraph. Here the input file is
simple text file.
Screenshot 1: Input file selection
2. Preprocessing(Remove Stemmer and stop words)
Following screenshot shows the processing in which stemmer is applied and the stop words like “a”,
“an”, “the” etc. are getting removed from the paragraph. Non-significant words are removed from the text.
Stemmer performs the process of reducing words to their stems, ie, the portion of a word that is left after
removing its prefixes and suffixes.
Screenshot 2: Stemming and Stop word processing
3. Preprocessing(POS Tagging)
Following screenshot shows preprocessing in which the Part of Speech Tagging to each
word,then the words in a sentence are divided and labeled with specific documentations like NNP for
Proper person noun, place or thing, NP for noun phrase, VP for verb phrase, and so on.

4. Summary Generation
Following screenshot shows final summary generation based on weight of each sentence, this system
will then select top weighted sentences as summary of all paragraphs or documents. Here based upon CQP
(Code Quantity Principle) we are giving score to each and every sentence, hence the sentences which are having
highest score among them, only those sentences will be processed into the paragraph.
Screenshot 4: Final Summary
5. Extraction of Elements
Following screenshot shows the extracted element like nouns, proper nouns, verbs etc. which are very
frequently used in the paragraphs. And these elements are the actual elements required to build or draw the E-R
diagram. These elements are nothing but the entities and their relationships.

V. Conclusion
Proposed system is used to create summary of given input datawhich is based on code quantity
principle.The input data is nothing but the English paragraphs, these paragraphs are processed and summery is
generated. This system termed as “Automated Conceptual Data Modeling” which Generates ER diagram
utilizing SBVR terminology on various sentences has been created for extracting the obliged data from the
naturallanguageinput which will be utilized to create a XMI document and thus produce an Entity Relationship
graph. In future distinct strategies of Entity Extraction can be used for enhancing exactness of ER graph.
For further enhancement of the given system, we can use different modelling tools for generating ER
diagram. The other enhancement is to work on sentence ambiguity for better result. This System can be further
Enhanced as a Web Application for generating Automatic E-R diagram.
