SOCIAL NETWORKING

  • The social network is a theoretical construct useful in the social sciences to study relationships between individuals, groups, organizations, or even entire societies.
  • Such networks provide an extremely suitable space to instantly share multimedia information between individuals and their neighbors in the social graph.

History Of Social Networking

  • In the late 1800s, both Emile Durkheim and Ferdinand Tonnies foreshadowed the idea of social networks in their theories and research of Social groups.
  • In the early 1930s Dr. Jacob Levi Moreno introduced the sonogram
  • In 1954, anthropologist  J. A. Barnes used the phrase “social network” to describe the complex relationships .

 Evolution graph of a social network:  Barabasi  Model

  • The Barabási –Albert (BA) model is an algorithm for generating random scale-free networks using a preferential  attachment  mechanism.
  • Scale-free networks are widely observed in natural and human-made systems, including the Internet, the world wide web, citation networks, and some social networks. The algorithm is named for its inventors Albert-Laszlo Barabasi and Reka Albert.

Social networks and science

  • Julia Porter Liebeskind et al. have published a study on how new biotechnology firms are using social networking sites to share exchanges in scientific knowledge
  • Social networking is allowing scientific groups to expand their knowledge base and share ideas, and without these new means of communicating their theories might become “isolated and irrelevant”.

Social networks and education

  • Social networks and their educational uses are of interest to many researchers. According to Livingstone and Brake (2010), “Social Networking Sites, like much else on the Internet, represent a moving target for researchers and policy makers.

Social Networking service

  •  A social networking service is a platform to build social networks  or social relations among people who, for example, share interests, activities, backgrounds, or real-life connections.
  •  Social networking sites allow users to share ideas, pictures, posts, activities, events, and interests with people in their network.

TENSE

Tense’ ৰ সন্মন্ধ হ’ল verb ৰ লগত । এটা বাক্য কোন tense ত আছে, সেই কথাটো আমি বাক্যটোৰ verb টোলৈ লক্ষ্য কৰিলেই গম পাওঁ । যেনে—

I go to school every day.

I went to school yesterday.

I shall go to school tomorrow.

Verbৰ ৰুপ নাইবা form সলনি কৰি আমি এটা sentenceক অন্য tense লৈ নিব পাৰো ।

There are three main Tenses:-

  1. The Present
  2. The Past
  3. The Future

The Present

  There are four present tense forms in English:

Tense Form
Present indefinite: I work
Present continuous: I am working
Present perfect: I have worked
Present perfect continuous: I have been working

  PRESENT INDEFINITE TENSE

     Verb ৰ ৰুপটো যদি “খাওঁ”, “খোৱা”, “খাৱ”, “খা”, নাইবা “খাওঁক” ৰুপত থাকে, ইংৰাজীত এনেবোৰ বাক্যক Present Indefinite Tense ৰ বাক্য বুলি কোৱা হয় । The  present indefinite  is a verb tense with two main uses. We use the simple present tense when an action is happening right now, or when it happens regularly. (বৰ্তমান কোনো এটা কমা কৰি থকা বুজাবলৈ আৰু অভ্যাস বশতঃ কৰা কামবিলাকৰ বিষয়ে present indefinite ত কোৱা হয় )

(ক) মই খাওঁ                       —      I eat.

(খ) তুমি খোৱা                     —      You eat.

(গ) তই খাৱ                       —      You eat.

(ঘ) তেওঁ খায়                      —      He eats.*

(ঙ) তেওঁলোকে খায়             —      They eat.

*Present indefinite tense ত subject যদি third person singular number হয়, তেনেহ’লে verb ৰ লগত s নাইবা es যোগ কৰিব লাগে । Depending on the person, the present indefinite  tense is formed by using the root form or by adding ‑s or ‑es to the end.

  1. Rana reads in class v. (Read+s=reads)
  2. He comes here every day. (Come+s=comes)
  3. The bus goes to Mangaldai every day. (Go+es=goes)

 

ঠিক সেইদৰে subject টো যদি third person singular number হয়, তেনেহ’লে have ৰ সলনি has হয় ।

  1. Arup has a pen.
  2. She has gone.
  3. It has been raining since yesterday.*

*It ক third person singular number বুলি ধৰি লোৱা হয় ।

PERSON

Person তিনিবিধ ।

First person:                                    I, We.

Second person:                                 you.

Third person:                                      যাৰ বিষয়ে কোৱা হয়, সেয়াই   third person.

He is my brother, Sugar is sweet, The boy were playing.

Pranjal is reading, Guwahati is beautiful.

NUMBER

Number দুইবিধ । Singular number আৰু Plural number. এটা বস্তু, এজন মানুহ, এখন ঠাই – মুঠতে এটা হ’লে singular হয় আৰু এটাতকৈ বেছি হ’লেই plural হয় ।

Singular Number – I, he, she, it, the boy, sugar, water, God, the school etc.

Plural Number – We, they, the girls, the schools etc.

Uncountable noun বিলাকক আমি third person singular number বুলি ধৰি লওঁ – rain, dust, air, love, water etc. গতিকে ইহতৰ লগত is/was/has ইত্যাদি ব্যৱহাৰ হয় ।

First-person singular: I write

Second-person singular: You write

Third-person singular: He/she/it writes (note the ‑s)

First-person plural: We write

Second-person plural: You write

Third-person plural: They write

ONE TIME ACTION AND HABITUAL ACTION

Habitually অভ্যাস বশতঃ কৰা কামবিলাকৰ বিষয়ে present indefinite ত কোৱা হয় ।

I often go to their home.

He eats rice in the morning.

I go to school every day.

Your sister speaks English well.

Birds fly in the sky.

He attends the office daily at ten.

The Present Indefinite Tense is used often with adverbs of frequency like ‘often’, ’usually’, ’generally’, ’daily’, ’once a week’, ‘every month’, ‘every year’ etc.

UNIVERSAL TRUTH

God is good.

The earth is round.

Man is mortal.

Present Indefinite Tense ৰ ক্ষেত্ৰত dose ব্যৱহাৰ:

     The formula for asking a question in the  present indefinite  is dose + [subject] + [root form of verb] Subject যদি third person singular number হয় আৰু বাক্যটোত যদি auxiliary verb নাথাকে তেনেহ’ল present indefinite ত main verb ৰ লগত s নাইবা es যোগ দিব লাগে । এনেকুৱা এটা বাক্যক প্ৰশ্নলৈ ৰুপান্তৰিত কৰিবলৈ হ’লে বাক্যটোৰ সন্মুখত dose বহুৱাব লাগে আৰু main verb ৰ লগত থকা s নাইবা es উঠাই দিব লাগে ।

He comes here every day.              Does he come here every day?

Raju lives in Guwahati.                   Dose Raju live in Guwahati?

His sister plays tennis.                      Dose his sister play tennis?

NEGATIVE WITH DOESN’T

    The formula for making a  present indefinite verb negative is does + not + [root form of verb]. You can also use the contraction  doesn’t instead of  does not. Third person singular number ৰ ক্ষেত্ৰত doesn’t হব । আৰু main verb ৰ লগত থকা s নাইবা es উঠাই দিব লাগে ।

Raju comes every day.                    Raju doesn’t come every day.

She likes sweets.                               She doesn’t like sweets.

Present Indefinite Tense ৰ ক্ষেত্ৰত do ব্যৱহাৰ:

Subject যদি third person singular number নহয়, তেতিয়া এনে বাক্যক present indefinite tense ৰ sentence ক প্ৰশ্নলৈ ৰুপান্তৰিত কৰিবলৈ হ’লে বাক্যটোৰ সন্মুখত do বহুৱাব লাগে ।

You like music.                                            Do you like music?

They live here.                                             Do they live here?

NEGATIVE WITH DON’T

I like sweets.                                    I don’t like sweets.

We live in Guwahati.                    We don’t live in Guwahati.

You know.                                          You don’t know.

BIG DATA

  • Big Data may well be the Next Big Thing in the IT world.
  • Big data burst upon the scene in the first decade of the 21st century.
  • The first organizations to embrace it were online and startup firms. Firms like Google, eBay, LinkedIn, and Face book were built around big data from the beginning.
  • Like many new information technologies, big data can bring about dramatic cost reductions, substantial improvements in the time required to perform a computing task, or new product and service offerings.

What is BIG DATA?

•‘Big Data’ is similar to ‘small data’, but bigger in size

•but having data bigger it requires different approaches:
–Techniques, tools and architecture

•an aim to solve new problems or old problems in a better way
•Big Data generates value from the storage and processing of very large quantities of digital information that cannot be analyzed with traditional computing techniques.

Three Characteristics of Big Data.

1st Character of Big Data Volume

•A typical PC might have had 10 gigabytes of storage in 2000.
•Today, Facebook ingests 500 terabytes of new data every day.
•Boeing 737 will generate 240 terabytes of flight data during a single flight across the US.
• The smart phones, the data they create and consume; sensors embedded into everyday objects will soon result in billions of new, constantly-updated data feeds containing environmental, location, and other information, including video.

2nd Character of Big Data Velocity

•Click streams and ad impressions capture user behavior at millions of events per second
• high-frequency stock trading algorithms reflect market changes within microseconds
• machine to machine processes exchange data between billions of devices
• infrastructure and sensors generate massive log data in real-time
• on-line gaming systems support millions of concurrent users, each producing multiple inputs per second.

3rd Character of Big Data Variety

•Big Data isn’t just numbers, dates, and strings. Big Data is also geospatial data, 3D data, audio and video, and unstructured text, including log files and social media.
•Traditional database systems were designed to address smaller volumes of structured data, fewer updates or a predictable, consistent data structure.
•Big Data analysis includes different types of data

Benefits of Big Data

•Real-time big data isn’t just a process for storing petabytes or exabytes of data in a data warehouse, It’s about the ability to make better decisions and take meaningful actions at the right time.
•Fast forward to the present and technologies like Hadoop give you the scale and flexibility to store data before you know how you are going to process it.
•Technologies such as MapReduce,Hive and Impala enable you to run queries without changing the data structures underneath.

•Our newest research finds that organizations are using big data to target customer-centric outcomes, tap into internal data and build a better information ecosystem.
•Big Data is already an important part of the $64 billion database and data analytics market
•It offers commercial opportunities of a comparable
scale to enterprise software in the late 1980s

•And the Internet boom of the 1990s, and the social media explosion of today.
