सामाजिक नेटवर्क विश्लेषण सॉफ्टवेयर

सोशल नेटवर्क विश्लेषण (एसएनए) सॉफ़्टवेयर वह सॉफ्टवेयर है जो संख्यात्मक या ग्राफ़ आरेखण के माध्यम से नेटवर्क की विशेषताओं का वर्णन करके व्यवहार के मात्रात्मक विश्लेषण या गुणात्मक अनुसंधान सोशल नेटवर्क विश्लेषण की सुविधा प्रदान करता है।

अवलोकन

नेटवर्क में परिवार से लेकर कुछ भी शामिल हो सकता है, परियोजना टीमें, कक्षाएँ, खेल टीमें, विधायिकाएँ, राष्ट्र राज्य|राष्ट्र-राज्य, रोग वाहक, ट्विटर या फेसबुक जैसी सोशल नेटवर्किंग सेवा या यहाँ तक कि इंटरनेट पर सदस्यता। नेटवर्क में नोड्स के बीच प्रत्यक्ष संबंध या साझा विशेषताओं, घटनाओं में साझा उपस्थिति या सामान्य संबद्धता के आधार पर अप्रत्यक्ष संबंध शामिल हो सकते हैं। नेटवर्क सुविधाएँ व्यक्तिगत नोड (ग्राफ सिद्धांत), डायड (समाजशास्त्र), त्रय (संबंध) , टाई और/या किनारों, या संपूर्ण नेटवर्क के स्तर पर हो सकती हैं। उदाहरण के लिए, नोड-स्तरीय सुविधाओं में नेटवर्क घटनाएँ शामिल हो सकती हैं जैसे कि बीच की केंद्रीयता और केंद्रीयता, या व्यक्तिगत विशेषताएँ जैसे कि उम्र, लिंग या आय। एसएनए सॉफ़्टवेयर इन सुविधाओं को एजलिस्ट, आसन्न सूची, या आसन्न मैट्रिक्स (जिसे सोशियोमैट्रिक्स भी कहा जाता है) में स्वरूपित कच्चे नेटवर्क डेटा से उत्पन्न करता है, जिसे अक्सर (व्यक्तिगत/नोड-स्तर) विशेषता डेटा के साथ जोड़ा जाता है। हालाँकि अधिकांश नेटवर्क विश्लेषण सॉफ़्टवेयर सादे पाठ ASCII डेटा प्रारूप का उपयोग करते हैं, कुछ सॉफ़्टवेयर पैकेजों में नेटवर्क सुविधाओं को आयात और/या संग्रहीत करने के लिए संबंधपरक डेटाबेस का उपयोग करने की क्षमता होती है।

विशेषताएँ

नेटवर्क डेटा को समझने और विश्लेषण के परिणाम बताने के लिए सामाजिक नेटवर्क का दृश्य प्रतिनिधित्व महत्वपूर्ण है। विज़ुअलाइज़ेशन अक्सर नेटवर्क डेटा की गुणात्मक व्याख्या की सुविधा भी देता है। विज़ुअलाइज़ेशन के संबंध में, नेटवर्क विश्लेषण उपकरण का उपयोग नेटवर्क प्रतिनिधित्व के लेआउट, रंग, आकार और अन्य गुणों को बदलने के लिए किया जाता है।

कुछ SNA सॉफ़्टवेयर पूर्वानुमानित विश्लेषण कर सकते हैं। इसमें व्यक्तिगत स्तर के परिणामों की भविष्यवाणी करने के लिए एक टाई जैसी नेटवर्क घटना का उपयोग करना शामिल है (जिसे अक्सर सहकर्मी प्रभाव या छूत मॉडलिंग कहा जाता है), नेटवर्क परिणामों की भविष्यवाणी करने के लिए व्यक्तिगत स्तर की घटना का उपयोग करना जैसे कि एक टाई/एज का गठन (जिसे अक्सर होमोफिली मॉडल कहा जाता है) शामिल है) या विशेष प्रकार के त्रय, या अन्य नेटवर्क परिघटनाओं की भविष्यवाणी करने के लिए नेटवर्क परिघटना का उपयोग करना, जैसे समय 1 पर टाई गठन की भविष्यवाणी करने के लिए समय 0 पर त्रय गठन का उपयोग करना।
